This paper proposes a novel energy and power management algorithm for AC microgrid operating with limited power sources, to ensure power quality and stability of the main grid. In a microgrid system, the renewable energy sources (RES) are commonly associated with conventional power sources and energy storage devices, due to the variety of the former. However, how to utilize the RES and energy storage system to constantly and steadily supply the loads, further more how to supply extra power to or draw necessary power from the main grid, is an essential issue when there is limited power sources of the microgrid if without a conventional power source. This paper solves that issue through an energy management algorithm. Simulation is conducted and results verify the proposed method. © 2017IEEE.

Laboratory electrical discharges that produce non-thermal plasma are used more and more for microbiological decontamination, surface treatment and depollution by the means of decomposing some complex molecules or in the field of modern medicine. Each application requires a power supply particularly adapted to the plasma reactor type used. If the first applications of these discharges were designed mostly for reactor types with high volume discharge capabilities, and the power supplies were simple and robust generating high power using industrial frequencies, in time the reactors decreased significantly in size and the power supplies used were working on higher frequencies. This trend was adopted on one hand out of the need for energy optimization of the power supplies used, and on the other hand for obtaining a better homogeneity of the treatment. This paper aims to provide a comparison of few AC and pulsed power supplies, working at different frequencies, with respect to the electrical parameters, from the point of view of active species production. The measured electrical parameters of the electrical discharges are the power and the specific energy. Also the results obtained for treatment of distilled water using three types of plasma reactors (classic GlidArc, Mini-torch plasma and Gliding Spark) will be shown. The analysis focus on the modification of pH of the distilled water in time after the plasma treatment.

The wearable devices technology has evolved dramatically in many respects over the last decade, e.g., in the accuracy and quality of the data provided, as well as the number of parameters measured. This created new opportunities not only in the fitness domain, but also in the well-being and general health. Indeed, each day, an ever-increasing number of people are interested in monitoring their daily habits and activities, as well as their physiological and psychological condition, aiming to improve their overall quality of life. Such tasks can be realized by the use of predictive tools that can guide and support individuals during their daily living activities. In this regard, wearable devices produce large volume of data, which should be properly analyzed in a fast and personalized manner. Furthermore, in order to provide the individuals with more effective and actionable information, other individuals and health professionals should be involved in the process. Having this in mind, this paper presents a smart health collaborative approach that considers the extensive analysis of the individual's wearable data, as well as a health social network to provide an infrastructure for the individuals to manage their data and easily interact with others individuals and physicians. The experiments focused on the data analysis module and considered data from four elderly individuals, wearing a Fitbit Charge HR. A clustering analysis was performed to identify and characterize patterns in their physiological behaviors and daily activities that were used for the prediction of the individuals' daily conditions and activities.

IOP Conference Series: Materials Science and engineering 2018年第2期400卷

作者： M Placzek M Mackowski Silesian University of Technology Faculty of Mechanical Engineering Institute of Engineering Processes Automation and Integrated Manufacturing Systems Konarskiego 18A 44-100 Gliwice Poland Silesian University of Technology Faculty of Automatic Control Electronics and Computer Science Institute of Informatics Akademicka 16 44-100 Gliwice Poland

This paper discusses the issue of dependability of a measuring system from the electromagnetic compatibility (EMC) point of view. During the tests, the equipment for conducting electromagnetic compatibility tests was used. The tests were carried out in accordance with the EMC Directive 2014/30/EU and the harmonized standard IEC 61000-4-6. The measuring system equipped with non-classical piezoelectric transducers called MFC was considered. The MFC transducer was used as a sensor connected to the NI 9191 CompactDAQ Chassis. During the research, the influence of conducted disturbances on the transmission wire was examined. One of the elements of the test bench was an EM-clamp (providing both inductive and capacitive coupling) consisting of a tube of split ferrite rings of two different grades, which can be clamped over the cable under test in a non-invasive way.

This paper addresses the problem of flocking of mobile robots by bounded feedback. A control problem is formulated with the multiple goals: velocity consensus, collision avoidance, and cohesion maintenance. The flocking protocol is then obtained by means of control design. Particularly, a Lyapunov-like function is presented, the velocity control is designed to achieve coordination and linear speed consensus, and the steering control is designed for consensus on orientation. The convergence is verified via Barbalat's lemma. Simulation results with a group of mobile robots are presented to show the effectiveness of the proposed flocking control.

Annual Conference of Industrial electronics Society

作者： Sertac Bayhan Panagiotis Kakosimos Haitham Abu-Rub Jose Rodriguez Department of Electrical and Computer Engineering Texas A&M University at Qatar Doha Qatar Department of Electronics and Automation Gazi University Ankara Turkey The Faculty of Engineering Universidad Andres Bello Santiago Chile

This paper presents a model predictive control (MPC) of five-level H-bridge neutral-point-clamped (NPC) quasi-impedance source inverter (qZSI). The proposed control technique is designed to handle three control objectives with simple and effective approach. The output current, the input current and the capacitor voltage are the control objectives of the proposed MPC algorithm. To fulfill these control objectives, multi-objective based cost function is employed. Furthermore, qZSI has been combined with the 5-Level H-bridge NPC inverter so as to obtain power converter topology with buck/boost and dc/ac conversion functionality in a single stage for high power PV applications. Simulation results verify the proposed multi-objective MPC algorithm and inverter topology.

IOP Conference Series: Materials Science and engineering 2017年第1期227卷

作者： M Płaczek M Maćkowski P Nowak Silesian University of Technology Faculty of Mechanical Engineering Institute of Engineering Processes Automation and Integrated Manufacturing Systems Konarskiego 18A 44-100 Gliwice Poland Silesian University of Technology Faculty of Automatic Control Electronics and Computer Science Institute of Informatics Akademicka 16 44-100 Gliwice Poland

The goal of presented work was to build an electronic device in order to test the effectiveness of different EMC-improving solutions. Three EMC tests were done in order to check the created device compliance with the electromagnetic compatibility directive. Each of them was conducted for both industrial and non-industrial parameters (voltage and field strength), according to IEC PN-EN 61000 standards. Three tests were done: conductive immunity test in EM clamp, radiated immunity test in GTEM chamber, radiated emission test in GTEM chamber. Firstly, the device's conductive immunity was examined. The set of possible solutions was created by examining existing designs, papers, books and producers' recommendations. In result, different component configurations were chosen to determine the most EMC-effective one. Next, electromagnetic compatibility of proposed device configurations was tested in the GTEM chamber (radiated immunity and radiated emission). Tests results are presented on charts and analysed in order to verify if designed device face requirements of the electromagnetic compatibility directive. It was verify which of proposed electromagnetic compatibility improving solutions can solve problems with electromagnetic compatibility.

Light urban electric vehicles are an important target, both for the researchers and manufacturers. Concerning the motor's choice, more ways are investigated, but the most important is that as compact as possible solutions have to be used. In the top of the preferences, the permanent magnet synchronous motors (PMSM) and brushless DC motors (BLDC) are situated. These are preferred thanks to their high power density, high efficiency and low maintenance cost. Even the main manufacturing technology and associated power electronics are quite similar, they essentially differ in the controlling technology, simpler and more advantageous being the BLDC. As integration technology, the in-wheel motor technology seems to be the one which improves the safety, efficiency, weight, controllability and finally the costs. Even the control principle is very well defined, the practical implementation can be different. The paper deals with four different control strategies for the BLDC motors. They are compared as technical implications and performances. © ECMS Valeri M. Mladenov, Petia Georgieva, Grisha Spasov, Galidiya Petrova (Editors).
