【Abstract】 This paper presents the design of a fuzzy PID controller based on the T-S fuzzy model,and analyses the effects of both quantized factor and proportional factor on the system performance.This analysis can help forward laying down a fuzzy rule for the on-line adjustment of the quantized factor and the proportional factor,thus realizing the on-line self-tuning of the fuzzy PID controller.The simylation of an industrial process with time delay shows that the control algorithm can improve the dynamic performance of the system.更多还原
