非脆弱鲁棒PID控制器设计

Design of Non-fragile Robust PID Controller

为了验证鲁棒PID控制器的非脆弱性,利用已有的非脆弱PID控制器参数范围,根据鲁棒PID参数计算方法,给出非脆弱性和鲁棒性都较好的参数.发现了控制器的非脆弱性的获得是以牺牲其鲁棒性为前提的,该结论对非脆弱鲁棒控制器的设计具有指导意义.仿真结果表明:鲁棒PID控制器具有较好的非脆弱性.

In order to test the non-fragility of robust PID controller, the parameters of PID controller with satisfactory robustness and non-fragility are calculated according to robust PID parameter tuning method using the existed parameter ranges of non-fragile PID controller. It is found that the acquirement of non-fragility is at the cost of losing its robustness, which is of guidance to designing a non-fragile controller. Simulation results show that the robust PID controller has satisfactory non-fragility.
