永磁同步电机速度控制器的设计

Speed Controller of the Permanent Magnet Synchronous Motor

针对永磁同步电机(PMSM)伺服系统中存在着模型参数不确定性的问题,将永磁同步电机的控制问题转换为H∞混合的灵敏问题,根据H∞理论设计出控制器。仿真结果表明该控制方法使永磁同步电机控制系统具有很好的鲁棒性,能有效的抑制参数摄动对系统的影响。

To prevent disturbance resulted from parametric uncertainties of PMSM, this paper converted control problem of permanent magnet synchronous motor into H∞ mixed sensitivity problem, then design H∞ controller .The simulation results show that the robust stability and the disturbance rejection performance of the PMSM control system with the H∞ controller are better than that with PID controller.
