模糊PID控制器在恒压供水系统中的应用

在对传统PID 控制器分析的基础上，结合现代模糊控制理论,设计了一个自适应-模糊
PID 控制器，并将其应用于变频调速恒压供水系统中。它弥补了采用单纯PID 控制器，难以保证系统在任何工况条件下始终具有最佳的控制性能的缺点。经过仿真和实际运行，得到了较好的控制效果。

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 .
