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。文章提出了一种时滞系统的模糊控制方法,并在W.L.Bialkowski 1983年提出的混合模糊PID控制器的基础上对积分系数K I提出了一种自校正算法,提高了这种模糊控制的适应能力。经MATLAB仿真验证,该控制器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 Fuzzy control method for time -varying systems, and propose a self tuning algorithm for the integral coefficient KI based on the mixed Fuzzy - PID put forward by W, L. Bialkowski in 1983 ,which improve the fuzzy control＇s performance. 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.
