摘要
普通模糊控制不能对时变滞后系统进行有效控制 ,甚至使系统失去稳定 .在 W.L.Bialkowski 1 983年提出的混合模糊 PID控制器的基础上 ,提出了一种自补偿混合模糊 PID控制器 ,并在此基础上提出了一种对积分系数 KI进行自校正的算法 .经 MATLAB仿真验证 ,该算法具有良好的控制品质 ,适应对象参数大范围变化的时滞系统 ,且易于工程实现 .
A general Fuzzy-controller cann′t control time-varying delay systems effectively and even have the systems lose their stability. This paper presents a Self-compensating mixed Fuzzy control algorithm for time-varying systems based on the mixed Fuzzy-PID put forward by W.L.Bialkowski in 1983, and put forward a Self-tuning algorithm to tune the integral coefficient K I based on it. It is proved with the simulation of MTALAB and possesses a good control quality, which can be suitable to systems with time-delay and time-varying parameters. But it can be realized easily in engineering.
