FUZZY PI / PD CONTROLLERS: MATHEMATICAL MODELS AND ANALYSIS

B.M. Mohan
Dept. of Electrical Engineering
Indian Institute of TechnologyAbstract:Input-output relationships of linear PI / PD / PID controllers are well known to the control community. In this seminar, input-output relationships of some fuzzy two-term (PI or PD) controllers, their classification, their properties, and their suitability (or unsuitability) for control application will be addressed. As a matter of fact, input-output relationship of a fuzzy two-term controller is not unique as it depends on contributing factors like nature of fuzzy sets, nature of control rules, type of fuzzy AND and OR operators, type of inference method, and type of defuzzification method. So, depending on the nature of contributing factors, different fuzzy two-term controllers are possible. It is very important to note that not all these fuzzy controllers are suitable for control. In order to decide about their suitability for control application, these controllers are analyzed and their characteristic behaviors are studied.Bio:B. M. Mohan was born in Tapeswaram, India in 1960. He received the Bachelors degree in Electrical Engineering from Osmania University in 1982, the Masters degree in Electrical Engineering (with Control Systems specialization) from Andhra University in 1985, and the Doctoral degree in Engineering from Indian Institute of Technology, Kharagpur, 1989. From July 1989 to October 1990 he was on the faculty of Electrical and Electronics Engineering Department, Regional Engineering College (now called National Institute of Technology), Tiruchirapalli. Since November 1990 he has been on the faculty of Electrical Engineering Department, Indian Institute of Technology, Kharagpur. He is currently a Visiting Professor at the Department of Electrical Engineering – Systems, University of Southern California, Los Angeles, California. His research interests include Identification, Analysis, and Control of Dynamical Systems using Fuzzy Logic and Orthogonal Functions approaches. He co-authored the research monograph 'Orthogonal Functions in Systems and Control (World Scientific, Singapore, 1995),' and several papers in international journals and conferences. He is a life member of Systems Society of India, senior member of the IEEE, and life fellow of Institution of Engineers (India). He is the Associate Editor of Int. J. Automation & Control (IJAAC). He is the reviewer for Computing Reviews. He was the Chairman of Control Systems Chapter, IEEE Kharagpur Section.Host: Prof. Petros Ioannou, Ext. 04452 http://engineering.usc.edu/calendar/
