摘  要：研究对象为面贴式的永磁同步电动机（SPMSM），针对MRAS在速度辨识时受电机参数影响较大的特点，将SPMSM本身作为参考模型以减少系统模型参数，利用定子电压、电流方程得到可调模型，并在辨识转速的同时，加上对转速辨识精度影响较大的定子电阻的在线辨识。采用SVPWM控制对该方法进行仿真，仿真结果表明该方法能够获得理想的转速辨识精度和动态性能。

Abstract: The subjects for surface permanent magnet synchronous motor (SPMSM), MRAS speed identification for the time influenced by the characteristics of the motor parameters will take SPMSM as a reference model to reduce the system model parameters, using the stator voltage and current equation adjustable model, and in recognition of the same speed, combined with speed identification greater accuracy of the stator resistance online identification. SVPWM control method using the simulation results show that the method can achieve an ideal speed identification accuracy and dynamic performance.
