针对传统控制方法在永磁同步电机矢量控制中存在的硬件要求高、低速运行时效果不好、没有考虑定子电阻变化等问题，在模型参考自适应系统（MRAS ）基础上，设计了新的自适应律，对电机的转速和定子电阻进行实时辨识，并应用该算法建立了Matlab仿真平台，仿真结果表明，改进的MRAS模型在定子电阻变化时，电机运行正常，证明了该算法的有效性和优越性。

Aiming at the probelm in the permanent magnet synchronous motor(PMSM)vector control with high demand of hardware,bad effect of low speed and no regard for changes of resistance,on the basis of model reference adaptation system(MRAS)model,a new adaptive law was designed to implement real-time identification of rotational speed of motor and stator resistance.A Matlab simulation platform was estab-lished by the application of this algorithm.The simulation results indicated that the improved MRAS model could operate when stator resistance had changed.Compared with the simulation result of the traditional MRAS model,the effectiveness and superiority of the algorithm were proved.
