摘　　要：针对恒压供水控制系统非线性、大滞后、参数时变的特征,结合模糊控制鲁棒性、免疫控制的自适应和常规PID控制的广泛性特点,设计了模糊免疫PID控制器。采用免疫控制对K_p进行自适应调整,模糊控制对K_i、K_d参数整定。仿真结果表明,该方法提高了系统的抗干扰能力和鲁棒性,具有较好的动态和静态性能。Aiming at the characteristics of non-linearity,large delay and time-varying parameters of constant pressure water supply control system,combined with characteristic of robustness,adaptive immune control and the universality of conventional PID control,a fuzzy immune PID controller was designed. Kp was adaptively adjusted by immune control,and the parameters of Ki and Kd were adjusted by fuzzy control. The simulation results showed that this method could improve the anti-jamming ability and robustness of the system,and show better dynamic and static performance.
