The method sets systemdisturbance within the feedback gain matrix f, which can be computed by iteration, in order to make the closed loop system optimum.
Through simulation experiments, although the conventional PID controller is designed simple, the ability to reject systemdisturbance and robust is rather weak.
通过仿真实验,常规pid控制器虽然设计简单,但对系统扰动的抑制能力较弱,鲁棒性差。

Therefore has the necessity to carry on the discussion to in the frequency changer application systemdisturbance question, promotes it further promotion application.
