摘 要：针对受参数不确定性和负载扰动影响的永磁同步电机速度控制问题，采用二阶滑模控制的螺旋算法来设计速度控制器，并利用实时鲁棒微分器来估算控制器所需要的转速微分信号。这种二阶滑模控制方法将不连续控制作用滑模量的高阶微分上，理论上可以消除抖振。仿真和实验结果表明，该方法对于负载扰动和参数的变化具有较强的鲁棒性，同时也有效地削弱了抖振现象。

Abstract: The speed control of permanent magnet synchronous motor was subjected to parameters uncertainties and load disturbances,and also designed a speed control law based on sliding mode control twisting algorithm.And a realtime robust differentiator was designed to estimate the input signals of the control law.In this approach,the discontinuous control effects were acted on the higher order differential of the sliding mode and the chattering could be eliminated theoretically.The simulation results show that the approach has very strong robustness to anti disturbance and parameters varieties,and the chattering is attenuated as well.
