| 摘 要： | 针对永磁同步电机多个参数同时辨识时会出现欠秩的情况,介绍了在dq坐标系下采用最小二乘法将多个参数分开辨识的方法。在硬件在环平台上采用该方法对电阻、电感和磁链进行了辨识。最后进一步考虑到电阻和磁链受温度的影响较大,进行了考虑温升的电阻和磁链的辨识。经验证,该方法可以比较准确地辨识出电机参数。

| Abstract: | For the case that owe rank may be caused in the multiple Parameters Identification of PMSM, a method that multiple parameters were identified individually using least square method was introduced. Then the resistance, inductance and flux linkage were identified based on recurrence least square (RLS) and hardware in the loop (HIL) platform. Finally , considering the great temperature influence, the resistance and flux linkage were identified. The method was verified that it could accurately identify the motor parameters. |
