摘　　要：为了提高永磁同步电机的速度控制性能,提出一种基于高增益转矩观测器的永磁同步电机滑模速度控制方法。首先,给出永磁同步电机的机械运动模型;接着设计了高增益转矩观测器,实时估计负载转矩;然后提出永磁同步电机滑模速度控制方法,并通过估计转矩对滑模速度控制策略进行前馈补偿,得到基于高增益转矩观测器的永磁同步电机滑模速度控制方法;最后在MATLAB/Simulink中进行仿真实验,验证了所提方法有效性。In order to improve the performance of permanent-magnet synchronous motor(PMSM)system,a high-gain load torque observer based on sliding mode speed control is proposed in this paper.Firstly,a mechanical PMSM model is presented.Secondly,a high-gain load torque observer is designed to estimate the load torque in real-time.Thirdly,a sliding mode speed controller is given for PMSM systems,and the observed load torque is fedforward to the controller to compensate the disturbance.Finally,a simulation is performed in MATLAB/Simulink to verify the proposed method.
