说明：  基于MRAS模型参考自适应的永磁同步电机PMSM在线参数辨识MATLAB仿真模型，可辨识电机定子电阻、电感和永磁磁链，辨识精度比较高。
(Based on the MRAS model reference adaptive PMSM on-line parameter identification matlab simulation model, the stator resistance, inductance and permanent flux can be identified, and the identification accuracy is relatively high.)
