摘要：

In this paper, a new tuning method based on gain margin, phase margin and ITAE index is proposed to determine the parameters (weighting factors) of fuzzy PI controllers with the simplest structure. With the proposed formula, the fuzzy PI controller is tuned appropriately such that it can be applied to different processes modeled approximately as first order plus dead-time dynamics. Numerical and experimental studies show that better performance has been achieved for both set-point change and load disturbance. (C) 1996 Elsevier Science Ltd.
