该文针对温度控制系统非线性、大滞后、参数时变的特征,设计了模糊免疫PID控制器.该控制器结合了模糊逻辑、免疫机理以及PID调节的各种优点,既具有模糊控制的非线性作用,又具有免疫控制的自适应能力,同时还具有PID控制的广泛适用性.文章介绍了模糊免疫PID控制器的控制原理和设计方法,在Matlab中编写函数仿真,结果表明该控制器能够实现持续干扰情况下的闭环鲁棒稳定,并使系统呈现良好的动态和静态性能.%Temperature control systems are characterized as non-linear,large time-delay and time-varying parameters.This paper designs the fuzzy immune PID controller for them.The controller absorbs all kinds of good points in fuzzy logic,immune mechanism and PID tuning.It combines nonlinear effects in fuzzy control,adaptive ability in immune control and broad application as PID control.The paper introduces the control principle,design approach and Matlab simulation of fuzzy immune PID controller.The simulation result shows that the controller can guarantee the closed-loop robust stability with continuous interference and make the system work,well in both dynamic and static state.
