Brief Description of Tutorials:
Current-fed converters are suitable for low voltage high current applications. Current-fed converters In addition, inductor is reliable compared to electrolytic capacitor along with higher lifetime (relatively reduced degradation). Alternative energy sources output (solar PV, fuel cells) is low voltage and the same is true for storage. Current-fed transformerless converters are able to boost 10x. In addition, the variability of renewables varies voltage and current (so the power) output. Therefore, the power electronics interface should accommodate such variations with high performance over entire operating range. The major challenge is maintain high efficiency with intermittent variability, load profile, and usage. Current-fed converters are superior in performance for such conditions and specifications. The major challenge in current-fed is high voltage spike/overshoot across the semiconductor devices at turn-off owing to hard commutation. It needs additional snubber circuits reducing density as well as boost capacity. In addition, the clamped device voltage is generally higher than desired. It limits the design flexibility and demands for high voltage devices resulting into higher conduction losses. We propose a novel modulation technique that achieves soft-commutation and natural voltage clamping of the devices without external snubber circuit making it snubberless while preserving the boost capacity. It solves the traditional problem of current-fed converters. The proposed modulation has been implemented and successfully demonstrated over several current-fed topologies to achieve the similar desired results. Proposed modulation permits the converters to operate under synchronous rectifier mode to improve the efficiency. Soft-switching of all semiconductor devices is achieved and maintained over wide variation in source voltage and power. Similarly, the attributes of natural device voltage clamping and soft-commutation are also maintained. The device voltage is independent of duty cycle but is clamped at reflected output voltage and can be varied by transformer turns ratio. It permits the flexibility in design and then selection of semiconductor devices to result into least conduction losses to develop an optimal high efficiency converter. Conventional current-fed as well as voltage-fed PWM and resonant converters have soft-switching limitations and lose at light load and increased source voltage. Therefore, it is quite obvious that these converters cannot maintain for entire operating range of solar panel, fuel cells, batteries, etc. However, the proposed current-fed converters maintain their originality owing to proposed modulation. Soft-switching, natural voltage clamping, and soft-switching are inherent and maintained with wide variation in source voltage and output power. Once designed at minimum voltage and maximum power condition, it maintains the given attributes guaranteed without additional auxiliary transition circuit or resonant tank. As additional measures, proposed topologies report negligible circulating current that results in higher efficiency at partial load and increased source voltage, reduced peak current stress across the components and requires low kVA rating devices and magnetics. High performance has been demonstrated compared to conventional voltage-fed resonant and PWM, and hard-commutated current-fed converters with active-clamping or snubbers. Major applications include interfacing low voltage dc and high voltage dc grids in a microgrid, MPPT, renewable energy integration, energy storage, and electric transportation.

Brief Description of Tutorials:
The operating characteristics of permanent magnet synchronous motors designed for the application in automotive traction drives are considerably different compared to the ones of industrial drives. The main characteristics are high magnetic saturation, high electrical fundamental frequencies with respect to the converter switching frequency, a wide constant-power operation range and a nonlinear reluctance torque. For the current controller design a suitable discrete-time motor model is required considering the impact of saturation and cross-saturation effects and a small number of sampling instants per electrical fundamental period. Furthermore, the motor model needs to describe the interaction between the discrete-time controller operation and the nonlinear magnetic motor characteristics. Based on that model deviation, a field-oriented current controller with a suitable decoupling of the current components can be designed. Two controller design variants will be presented: a current controller with constant parameters, that is robust to varying plant time constants due to saturation effects, and the design of an adaptive controller, which parameters are updated using a simplified saturation characteristic model. It will be shown by measurement results that the adaptive controller has a better reference response and disturbance reaction in operation points with low magnetic saturation.
To ensure a high efficiency, an operation point selection that provides appropriate current reference values with respect to the demanded torque is required. This torque control has to be realised in an open-loop manner, since power and torque measurements are not available in automotive applications. Here, a state-of-the-art ME (Maximum Efficiency) operation strategy will be compared to classical MTPC (Maximum Torque per Current) approaches. The impact of the loss characteristics of a given motor, the restrictions due to current and voltage limits and the relevance of different operation points with respect to a specific driving cycle will be discussed. Additionally, a superimposed voltage controller taking varying DC-voltages and parameter uncertainties into account will be presented. This additional controller is required to ensure maximum voltage utilisation beyond base speed while guaranteeing the viability of the inner current control loop by providing a voltage reserve margin.
Highly dynamic and stochastically load profiles in automotive applications are making it almost impossible to estimate the temperature characteristics regarding critical motor components, e.g. the stator winding or the permanent magnets, during the drive design phase. Measuring these temperatures is costly and thermal sensors are potential error sources leading to enormous repair efforts in the failure case. Against this background, real-time capable methods to observe critical motor temperatures have to be considered within the motor control software. A suitable temperature estimation will be the basis for a derating controller that is required to prevent device failures due to thermal stress while utilising a given motor to a maximum thermal extent. In addition, certain electrical motor model parameters are temperature sensitive and adapting these within the control software leads to an increased control performance and accuracy.

Brief Description of Tutorials:
Energy efficiency in DC-DC converters, protection of electronic circuits against short duration high voltage transients, rapid energy transfer at high power into a fluid flowing through a pipe and increasing the power density of inverters could be identified as some traditional problems is electrical engineering. Non-traditional supercapacitor assisted circuit topologies were developed as unique circuit solutions to these traditional problems.
Commercial supercapacitors are available from fractional farads to over 5000F as low-voltage single-cells, and, in module form for voltage ratings over 100V today. These devices have high power density compared to batteries due to their relatively constant and very low equivalent series resistance, but their energy density is one order lower than rechargeable chemistries. Traditional applications of these devices are in battery-supercapacitor hybrids used in UPS and power quality enhancers, wind energy systems, hybrid electric vehicles, portable devices and in powering memories.
First 30 minutes of the tutorial will provide an overview of commercial supercapacitor families and their capabilities and limitations, comparing them with rechargeable battery chemistries including a short practical demonstration on the capability of a 3000 F order single cell device.
In the second 90 minutes of the tutorial, an introduction to patented or patent pending new circuit topologies such as (i) supercapacitor assisted low dropout regulators (SCALDO) (ii) supercapacitor assisted surge absorbers (SCASA) (iii) supercapacitor assisted temperature modification apparatus (SCATMA) and (iv) supercapacitor assisted high density inverter (SCAHDI) will be presented. Required characterisation of these supercapacitors for these new applications will be included.
SCALDO is a technique where a SC is used as theoretically lossless voltage dropper in the series path of a LDO where energy recirculation happens at a very low frequency range of mili-hertz to fractional hertz, eliminating the RFI/EMI issues. It is not a variation of charge pumps and the technique's capability is identified by a efficiency multiplication factor. For a 12-5V case this factor is 2 and for 5 to 1.5 V and 5 to 3.3V it is 3 and 1.33 respectively.
SCASA is a short-term high-voltage transient-surge absorption technique based on a SC based sub-circuit absorbing part of the transient energy in surge protector. This is capable of minimizing the components required in a surge protector circuit.
SCATMA is a technique developed to fast-heat the water flowing into the water faucets in domestic situations to avoid the waste of water due to long buried pipes in walls. This can save huge amount of daily wasted water due to delays in hot-water supply.
SCAHDI is a supercapacitor assisted technique for improving the power density of inverters usable in renewable energy applications, where the fundamental energy loss associated with the charging of an (partial or fully) empty capacitor using a voltage source. This technique is expected to assist reducing the input ripple current in an inverter.
All these SC assisted techniques are outputs of a unique research program on-going at the University of Waikato under the leadership of the sole presenter, and most of these works are covered by issued or pending patents. Presented work is also covered by many IEEE/ IET publications within the period of 2009 to 2015.

Brief Description of Tutorials:
Cyber-Physical Systems (CPS) refer to ICT systems (sensing, actuating, computing, communication, etc.) embedded in physical objects, interconnected through several networks including the Internet, and providing citizens and businesses with a wide range of innovative applications based on digitalized data, information and services. We are witnessing today several concepts and technology trends when designing and implementing solutions on Industry Cyber-Physical Infrastructures e.g., the Internet-of-Things, the SmartGrid, the Factory of the Future, the Industry 4.0, etc. Especially when key issues on cross-layer collaboration, (near) real-time interaction, complexity and emergency behaviour management, support of system of systems evolvability, heterogeneity, interoperability, scalability etc. are coming into play, we have to radically rethink engineering approaches under the requirements and constraints of the Industrial Systems. Structural Integration and Behavioural Collaboration are major goals especially for a domain relative new to IT technologies and their rapid evolution pace. A digitalization of the industrial environment based on Service-oriented Architectures (SoA), Web and Cloud Computing Technologies, among others, have been proven to be a real and feasible innovation backbone at Internet scale, and are finding their way in the future Industrial Systems, allowing the realization of the Internet-of-Automation-Things.
Based on Lessons learned from latest prototype industrial applications, we need to further evaluate and assess the capability and applicability of the implemented approaches, and ask for scientific, technological and also social key questions e.g., how deep can we go with web technologies in real-time monitoring and control; how can we realize the next generation large-scale distributed monitoring systems; how to support the lifecycle of industrial solutions viewed under the system of systems engineering viewpoint; how to architect the next generation distributed automation and management systems; what is the trade-off for security, trust and privacy; how can we migrate towards digitalized smart industrial collaborative systems; how to design today the best legacy system of tomorrow; how to support the integration into and the interaction of the human with the digitalized industrial world (the machine operator, the line supervisor, the system maintenance, the planner, the production manager, are also digitalized “THINGS"), etc.
The tutorial aims at providing an insight to aspects such as: major industrial requirements and challenges to innovate in designing, implementing, deploying and operating ICPS; which Information-Communication-Automation paradigms and associated technologies are supporting those innovations? e.g. web services on devices, integration with enterprise systems (MES/ERP), collaborative service- and agent-based automation, future cloud-based SCADA/DCS, engineering large scale digitalized industrial systems of systems, migration of legacy industrial infrastructures, etc. We aim to strike the balance in providing lessons learned, hands-on experiences as well as future directions, aspects of interest and challenges.

Brief Description of Tutorials:
This tutorial covers basics, theories, and applications of motion control technologies, and is organized by four talks below.
The first talk entitled "Control of Smart Material Actuators with Hysteresis" is given by Dr. Ruderman. Smart materials, also known as active or functional materials, exhibit in general a mechanical response when being subject to an acting external field like mechanical, thermal, electrical, magnetic, optical, etc. It is known that an accurate control of smart material systems often showing nonlinearities, hysteresis, and creep effects, among others, requires an advanced modeling and related control design. The presentation contains several aspects of hysteresis modeling in context of the overall system dynamics, model-based and model-free control design, and adaptive extensions to cope with a time-varying smart material behavior. Experimental examples from the piezoelectric and magnetic shape memory based actuators will be shown along with discussion.
The second talk is “Optimal Control Applications in Vehicle Dynamics” that will be presented by Prof. Biral. In this talk, the general theory and the numerical implementation methods and issues of the Pontryagin Minimum Principle (PMP) are introduced and discussed with examples in the automotive fields. Recent advances in theory, algorithms and computational power make it possible to solve complex practical optimal control problems both for off-line and on-line applications. The talk focuses on an Indirect Method based on the Pontryagin Minimum Principle (PMP), and presents a detailed procedure and software tools, and finally numerically solve several optimal control problems of practical relevance. Application examples will be presented and discussed for energy management of a vehicle with hybrid propulsion system, obstacle avoidance and minimum time manoeuvring.
The third talk focuses on vibration control of motion control systems and its application to high-precision positioning systems, and is presented by Prof. Seki. Fast and high precision positioning is one of indispensable techniques in a wide variety of high performance mechatronic systems from the viewpoints of high productivity, high quality of products, total cost reduction, etc. Since most of mechanisms inherently include mechanical vibration modes, the resonant vibration due to the modes prevent the control performance. In this presentation, we will discuss the vibration suppression approaches in feedback and feedforward controller design. Some approaches and experimental results will be shown by using a typical positioning device for galvano scanner in laser drilling machines.
The fourth talk is entitled “Development of Medical and Rehabilitation Robots based on Haptic Motion Control Technology”, and is presented by Prof. Shimono. In this talk, applications of haptic motion control technology to medical and rehabilitation robots are discussed. Haptic feedback function is quite important not only for performance improvement, but also for evaluation of human motion based on force information. This talk introduces some results on new medical robots, clinical test by robotic rehabilitation, and so on. Additionally, future prospects of development of new medical and rehabilitation robots based on new actuation techniques will be presented.
This tutorial is supported by Technical Committee on Motion Control in IEEE Industrial Electronics Society (IES).

Brief Description of Tutorials:
Thanks to the increasing switching frequency of the conversion circuitry, size of the passive components such as transformer and filters has been shrunk, thus achieving higher power density. As a return, the relevant switching devices are subjected to higher switching losses and stresses. They can be abated by turning-on and/or -off the switches when the voltage across and/or the current through them is zero. Such a mechanism, collectively termed soft-switching, is known as zero-voltage-switching (ZVS) and zero-current-switching (ZCS) respectively. There are basically three families of soft-switching converters that differentiate for the circuital solutions. They are: 1) resonant-transition converters (RTCs), 2) quasi-resonant converters (QRCs) and multi-resonant converters (MRCs), and 3) resonant power converters (RPCs). RPCs are getting increasing interest nowadays due to their features of high-power density and high-efficiency, and will be the main issue of this tutorial.
The tutorial is divided into two parts. After framing the different soft-switching families, the first part will give a comprehensive overview on the RPCs. Their principle of operation is first introduced and then several RPC topologies with two- three- and four-elements (e.g. SRC, PRC, LCC, LLC and LCLC) are analyzed with regard to their performance such as input-output characteristics and efficiency. Moreover, the characteristics of each topology are discussed together with their merits and limitations.
The second part of the tutorial begins with the analysis of the main control techniques of the RPCs and of their effect on the RPC dynamics; it is followed by an overview on the impact of the technological progress in the power semiconductor devices on the performance of the RCs. The second part closes with design and implementation of RPCs for some study cases in the areas of power supply systems and renewable energy systems (e.g. photovoltaic, wind or fuel cells).

Brief Description of Tutorials:
During the last few years, the adoption of lithium ion batteries has become well established in mobile applications, as well as in stationary applications. In order to take full advantage of the superior performance characteristics of modern lithium ion batteries, advanced management is mandatory to ensure a safe and reliable operation of the battery and prolong its life. This tutorial aims at presenting current and future trends in the design of battery management systems (BMSs) for large-format lithium ion batteries, which consist of several series-connected elementary battery cells.
A primary function of a BMS is an accurate and fail-safe monitoring of the battery parameters. They include the voltage and temperature of each cell of the battery, as well as the battery current. For all these parameters, commercial solutions are available. Indeed, some of the integrated monitoring circuits on the market have already reached their 3rd or 4th generation and significant improvements have been made in measurement accuracy and communication robustness. However, competition on the market is growing and research in this field is ongoing. Important topics driven by the industry are safety functions and cost reduction (e.g., through reduced bill of materials for the monitoring circuit). Current research activities span from new monitoring architectures (such as cell integrated monitoring solutions using wireless or power line communication) to monitoring new parameters with online electro-chemical impedance spectroscopy (EIS) or optical sensors.
The acquired battery parameters are used to maintain all the battery cells in their safe operating area (SOA), as well as to estimate their internal state. The latter include the State-of-Charge (SoC) and State-of-Health (SoH) state variables. Their precise knowledge is fundamental for evaluating the residual energy stored in the battery, its capability of providing power to the load, and for realizing battery diagnosis and prognostics functions. This tutorial will provide a brief overview of the most used approaches for cell modeling and for SoC estimation. Then, focus will be moved to SoH estimation, which is an open and challenging research topic. Speakers' most recent research results on this field will be discussed and applied to range estimation in electric vehicles in the framework of big data technology.

Brief Description of Tutorials:
The world must solve important challenges to control and transform energy in an efficient way. Examples of this are in transportation, renewable energies and industrial processing applications. These problems can be solved using power converters based on modern power semiconductor devices. The ideal converter in many of these applications may have the following characteristics:
- i) Sinusoidal input and output currents.
- ii) Operation with unity power factor.
- iii) Regeneration capability.
- iv) Compact design with a good power to weight ratio.
All these characteristics can be fulfilled by Matrix Converters and this is the reason for the tremendous interest in this topology. In the last decade many advances in the development of this topology have been presented, including industrial applications up to megawatt levels. The use of Matrix Converters in real applications and the challenges that these applications present is very topical and important.

Brief Description of Tutorials:
Condition monitoring is of high concern in industrial applications since it minimizes the downtime and improves the reliability, availability, safety and productivity of these systems. For electrical motors and generators, faults detection and diagnosis is usually performed by vibration monitoring, temperature measurements, oil monitoring, flux monitoring and current analysis. Among these various techniques, current analysis has several advantages since it is a noninvasive technique that avoids the use of extra sensors. Moreover, the electrical signals (for instance, the stator current) are usually available and inexpensive to measure.
Stator currents processing-based faults detection and diagnosis of electric machines and drives has received intense research interest for several decades. Moreover, the International Standard “ISO FDIS 20958” dealing with “Condition monitoring and diagnostics of machine systems - Electrical signature analysis of three-phase induction motors” sets out guidelines for the online techniques recommended for the purposes of condition monitoring and diagnostics of machines, based on electrical signature analysis. Hence, many studies have shown that fault monitoring could be performed by supervising the current spectrum. Most of the used faults detection and diagnosis techniques perform spectral analysis, such as Fourier or MUSIC techniques. Although these techniques exhibit good results in stationary conditions, they are not well suited for a majority of electric machines and drives applications. Indeed, these applications environment is predominantly non-stationary due to transients or variable speed operations. In this context, the involved signals are usually non-stationary, embedded in noise, and can contain closely spaced frequencies. It is then obvious that faults detection and diagnosis in such applications are challenging tasks that need using specific signal processing tools.
In this challenging context, this tutorial aims to present the main advanced signal processing techniques for electromechanical systems condition monitoring (faults detection and diagnosis). It will focus on presenting these advanced tools from time-frequency representation and time-scale analysis to demodulation techniques. All these techniques will be evaluated and compared and their advantages and drawbacks highlighted. Afterward, it will be introduced the parametric spectral analysis, which aims to handle some of the main raised drawbacks.

Brief Description of Tutorials:
Effective and efficient services in healthcare have been facing challenging issues. At this point, there are 83 countries not fulfilling the threshold requirement of 23 skilled health professionals per 10,000 people. Based on the survey deducted by the World Health Organization (WHO), the world will fall short of healthcare workers by 12.9 million by the year 2035. biomedical technologies and applications need to be developed.
The advanced development of biomedical application is favourable to the nonconvex optimization techniques, in particular for wireless systems. In this tutorial, a few of our recent developments will be discussed. These include the detection of viral infections and bacterial infections based on cough sounds, the classification of supraventricular tachycardias and ventricular tachycardias based on electrocardiograms, …etc. In the most updated development, wearable devices are employed for the acquisitions of the electrocardiograms, the electromyograms and the blood glucose concentrations. These biomedical signals are sent to cell phones via wireless technologies. This can reduce the hardware implementation costs. On the other hand, the cough sounds are directly recorded through mobile audio microphones. Next, nonconvex optimization techniques are employed to perform the detections and the recognitions of various biomedical applications in the cell phones. Finally, the detection and the recognition results are displayed on the cell phones via graphical interface based mobile applications.
In this tutorial, an overview of the trends and techniques for biomedical Industrial applications will be discussed. The ICT infrastructure and the useful and popular algorithms for medical identification of various key diseases will also be briefed. In particular, special undated applications will be briefed. For instance, the detection of viral infections and bacterial infections based on cough sounds, the classification of supraventricular tachycardias and ventricular tachycardias based on electrocardiograms, the detection of Parkinson's diseases based on electromyograms …. etc are formulated as biomedical signal recognition problems. To perform the biomedical signal recognitions, some nonconvex optimization techniques are developed. First, instead of transforming signals in the time domain to the frequency domain via the conventional energy preserved matrices such as the discrete Fourier transform matrix and the discrete cosine transform matrix, general energy preserved transforms based on Hermitian matrices are employed. The features for performing the biomedical signal recognitions are chosen as the products of the transform coefficients and the mask coefficients. Here, the join design of the transform matrix and the mask coefficients are formulated as a quadratic matrix equality constrained optimization problem. To reduce the total number of features, the interclass separations are maximized and the intraclass separations are minimized. To yield high recognition rates, the perceptrons with the activation functions having multi-piece domains and multi-levels are employed. The design of the boundaries of the multi-piece domains is formulated as a sparse optimization problem. In fact, all these optimization problems are nonconvex. Analytical solutions of these nonconvex optimization problems are derived so that solutions of these optimization problems can be found in real time. Some computer numerical simulation results are demonstrated.
