摘　　要：针对工业中常规控制器难以达到较好控制效果的控制难点,提出了免疫PID控制器,利用模糊控制可以无限逼近非线性的特性,构成非线性模糊免疫PID控制器,并基于正交函数将MIMO(多输入多输出)控制系统的非线性模糊免疫PID控制器的设计过程转化为由一个只含有代数方程的算法来实现,最后用具有自适应功能的遗传算法对其进行优化。仿真结果表明,所设计的控制器在控制性能上优于常规PID,并能快速得到最优参数。另方面对于多输入多输出控制系统,控制器的设计和优化显得更为简便和有效。A nonlinear fuzzy immune PID control method is presented to solve the control difficulties of industry process. Based on orthogonality funetion, the nonlinear fuzzy immune PID design process for MIMO system is turned into a simple algorithm which only includes algebraic equation, and then optimized. This method has good control performance and obtains the best parameter faster than conventional PID control. On the other hand, the process of the design and optimization of this controller is simpler and more effective.
