Abstract：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.
