Abstract

The paper presents a methodology for simuiation study and real time implementation of a fuzzy logic based controller of a power elecíronic system. The fnay controLier with the membership functions and d e base is developed and programmed for simuiation in a high level language (mch as SIMNON) h the same environment as the plant and other non-fuzzy controller simulation, and then extensively iterated until optimum performance is obtained. The optimized controller is then directly translated to assembly (or c) language and integrated with the other controllers for real time implementation. The methodology is illustrated in detail with an actual control system.

was born in Faria Lemos, Minas Gerais, Brazil, on October 5, 1958. He received the BE. degree in electrical engineering from the Federal University of Espirito Santo, Brazil, in 1981, and the M.S. degree from the Federal University of Santa Catarina, Brazil, in 1986. In 1989 he was awarded a scholarship by the Brazilian Agency for Research and Development (CNPq) to pursue doctoral studies at the University of Tennessee, Knoxville, USA, where he got his Ph.D. in 1993. He has been a member of the faculty at the Electrical Engineering Department of the Federal University of Espirito Santo, since 1982, where he has taught several courses in power systems, electrical machines and more recently, power electronics and drives at graduate level. He has recently started to act as a research supervisor at UFES' Master Program in Electrical Engineering. His research interests comprehend power electronics and drives, machine modeling and power systems planing. He has published several papers at both national and international conferences, as well as some papers in IEEE transactions. Dr. Sousa is a member of IEEE Industry Application Society, The Brazilian Power Electronics Society (SOBRAEP), and The Brazilian Automatic Control Society (SBA).

received the B. E. degree from Calcutta University, Calcutta, India, in 1956, the M.S. degree from the University of Wisconsin, Madison, in 1960, and the Ph.D. degree from Calcutta University in 1966. He was a member of the Faculty of Calcutta University, India, where he was awarded the Premchand Roychand Scholarship and the Mout gold medal for outstanding contributions. In 1971 he joined Rensselaer Polytechnic Institute, Troy, NY, as Associate Professor of Electrical Engineering where he was responsible for the power electronics program for five years. From 1976 to 1987, he was an Engineer at the General Electric Research and Development Center, Schenectady, NY, where he did extensive research in power converters, ac drives, microcomputer control, and the like. In 1987 he joined the University of Tennessee, Knoxville, as Professor of Electrical Engineering (Condra Chair of Excellence in Power Electronics). He is also the Distinguished Scientist of the Power Electronics Applications Center, Knoxville. He has published more than 120 papers and holds 18 US patents. He is the author of Power Electronics and AC Drives (Prentice-Hall, 1986) and editor of several other IEEE press books. Dr. Bose is Chairman of IEEE Industrial Electronics (IE) Society Power Electronics Council and has served as Associate Editor of the IE Transactions, as well as to other IEEE societies publications. He is also the recipient of several awards for his outstanding contributions to the Power Electronics and Drives technology.

Marcelo G. Simões, Escola Politécnica da Universidade de São Paulo PMC / Mecatrdnica Av. Prof. Mello Moraes, 2231 05508-900 São Paulo - SP

was born in São Paulo, Brazil, on February 03, 1963. He received his BE degree in Electrical Engineering from "Escola Politécnica da Universidade de São Paulo" on December 1985. Upon graduation he worked for FDTE, a research institution that belongs to The University of São Paulo, for three years. He has been a professor at the University of São Paulo (Brazil) since 1989, and obtained his MS degree in July, 1990, at the University of S3o Paulo. He was awarded a Brazilian scholarship to pursue his doctoral degree at The University of Tennessee, Knoxville. During his doctoral studies at The University of Tennessee, he published several papers in IEEE conferences, some of them were accepted for publication in IEEE Transactions. He has also two patents pending for the new strategies presented in his Ph.D. dissertation for control of drives and performance enhancement of wind generation systems. He received the Doctor of Philosophy degree in December, 1995, and now he is working as a professor at The University of São Paulo (Brazil), doing research and development of systems on the application of artificial intelligence in power electronics, drives, and machine control.
