摘要
针对微机过程控制系统被控对象非线性、不确定性和时变等特点,在微机过程控制系统中设计应用了模糊控制器.为了使算法更具鲁棒性,该模糊控制器在规则可调整模糊控制器基础上引入了加权因子α的在线调整优化算法.运行结果表明这种算法简便而有效.
On the basis of characteristics of non-linearity uncertainty and time-change, a fuzzy controller is applied in computer process control system. In order to improve its robustness, a method for on-line optimizing the weighting factor otis adopted fuzzy controller. Experimental result indicates that the method is in the applied rule-adjustable convenient and effective.
