Model following servo control for fuzzy linguistical systems
Shigeyasu Kawaji · Proceedings of IEEE 5th International Fuzzy Systems · 2002
In real applications, exact dynamic model of plants can be rarely obtained and the desired characteristics of the control systems are specified in the wide ranges. In order to get a satisfactory settlement of the problems, a new control system for fuzzy linguistical systems is presented in this paper which comprises two schemes: one is fuzzy model following servo control system which makes better use of human intuition and experiences for desired responses of the plant using the linguistic expression, and the another is a fuzzy observer which estimates the internal information of the plant from the external data. The effectiveness of the proposed method is shown for a nonlinear DC servomotor system.
