直流电机转速鲁棒控制器的研究

Research on robust controller for rotational speed of DC motor

提出一种新的直流电机鲁棒速度控制方法 ,该方法通过构造速度误差的Lyapunov函数 ,导出了可变反馈增益。为得到等效的负载扰动 ,设计一个负载扰动观测器 ,并在此基础上设计出转速鲁棒控制器。

The new method of robust controller is presented for rotational speed of DC motor ,and the method is constructed with the Lyapunov function of speed error,the variety feedback gain is edcued.In order to get equivalent load distubance,a observater of load disturbance is designed,and the rotational robust controller is designed on the base.The validity of the method is proved by computer simulation.
