在對傳統PID 控制器分析的基礎上，結合現代模糊控制理論,設計了一個自適應-模糊
PID 控制器，并將其應用于變頻調速恒壓供水系統中。它彌補了采用單純PID 控制器，難以保證系統在任何工況條件下始終具有最佳的控制性能的缺點。經過仿真和實際運行，得到了較好的控制效果。

Application of fuzzy PID controller on constant pressure water -supplying system WANG WEI1 , HU YING-ZHAN 2 (1.department of Computer Engineering. Henan Polytechnic Institute, NanYang , 473009,China; 2.department of Electrical Engineering. Henan Polytechnic Institute, NanYang , 473009China) Abstract:Based on the analysis of traditonal PID controller and combining with modern fuzzy control theory, A self-adaptive Fuzzy-PID controller is designed and applied to VVVF constant presure water-supplying system. It makes up the shortcoming of single PID controller which can not assure the best control performance for system in diffierent working condition. It has better effects by stimulatiuon and actural running .
