摘要
为了增强直流调速系统的抗扰动能力和鲁棒性能,提出了一种基于生物体免疫反馈机理的模糊免疫PID控制器.该控制器由一个PID控制器和一个基本的免疫型比例控制器顺序串联而成,免疫型比例控制器中的非线性函数由模糊推理来实现.利用Matlab/Simulink对闭环调速系统进行仿真,结果表明,与常规的PID控制器相比,该系统具有调整时间短、抗扰动能力强、鲁棒性好等优点.
A fuzzy-immune PID controller based on the disturbance rejection ability and robustness of DC motor immune feedback law is proposed to enhance the speed-regulating systems. This controller consists of a PID controller and a basic immune proportional controller in cascaded connection and the non-linear function of the immune proportional controller is realized by using fuzzy reasoning. Simulation results with Matlab/Simulink demonstrate that the closed-loop speed-regulating system with this proposed controller has shorter settling time, stronger disturbance rejection ability and higher robustness compared with the corresponding linear PID controller.
