On the experimented equipment of single-stage tank liquid-level and system software platform,classical PID control and Fuzzy control and parameter self-tuning PID control have been applied to the single-stage control object.
Two Fuzzy-PID controlling methods are proposed to control the electronic heating temperature:Fuzzy-PID threshold control and Fuzzy-PID self-tuning parameter control. Two kinds of Fuzzy-PID temperature controller were designed and simulated by Matlab.
As to the Fuzzy-PID self-tuning parameter controller,first the self-tuning PID parameters(K_P,K_I,K_D,)were obtained by fuzzy logic rules, then the improved PID controller was used to control the whole system.
This article applies self-tuning parameter FUZZY-PID arithmetic to temperature control system of resistance furnace,and the arithmetic is the integration of fuzzy and PID control technique,it possesses both the flexible and strong robust advantage of fuzzy control and the precise character of PID control.
This paper,taking ship fin stabilizer control system as an object,applying fuzzy control theory,has come up with a PID parameter self-adjusting controller based on fuzzy reasoning,so as to realize the theory of on-line controller parameter fuzzy sel-adjusting.
This study consists of two sections: The first one is that control qualities and robustness in the application of the simple fuzzy controller, the fuzzy controller of parameter self-adjusting and the fuzzy-complex controller of parameter self-adjusting to the servo system are studied by simulation and the second one is the study of the actual servo system.
