本文提供了一种基于滑模观测器的永磁同步电机矢量控制系统的实施方案。设计一滑模观测器,对永磁同步电机的转子位置角和转速进行实时在线估算,实现电机的闭环调速运行。仿真结果表明,本文提出的这种滑模观测器对系统参数摄动、外干扰以及测量噪声具有的极强鲁棒性,有效地改善系统的动、静态运行性能。

This paper presents the implementation of sliding mode observer for vector control of Permanent Magnet Synchronous Motor （PMSM）.In order to achieve closed loop operation of the motor, the stator magnetic field should be vertical with the rotor magnetic field and be synchronous with rotor rotating, so the position and speed of PMSM is real-time estimated. Simulation results verify that the proposed control scheme significantly shows robust to motor parameters uncertainty, disturbance and measurement noise. It effectively improves dynamic and static operation performance.
