摘　　要：针对传统P ID控制器存在的问题,设计了一种模糊自适应整定P ID控制器,利用模糊推理方法实现对P ID参数的在线自整定,进一步完善了P ID控制器的性能,提高了系统的控制精度。仿真结果表明,该控制器明显地改善了控制系统的动态性能,便于工程应用。Aiming at the problem that conventional PID controller exists, a self-adaptive adjusting of fuzzy PID controller is proposed. The using of fuzzy logic controller makes the parameter＇s self-adaption of PID controller possible,it also perfects the properties of PID controller and improves the precision of control system. The result of simulation indicates that the controller evidently improves the dynamic property of control system. The controller is easily applied in engineering.
