摘　　要：详细介绍了一种永磁同步电机(Permanent Magnet Synchronous Motor,简称PMSM)矢量控制系统电机参数的离线辨识技术。该技术基于电机的动态数学模型,通过在电机端注入直流或交流电流,测量相应的电压响应,辨识出电机的定子电阻、转子磁链、直轴电感和交轴电感。实验结果证明了该算法的正确性。An off-line parameter estimation technique to determine the parameters which are necessary to implement the vector control of the permanent magnet synchronous motor （PMSM）is presented.Based on the motor dynamic model motor,a DC or an AC current is injected into the motor,and then the stator resistance,rotor flux linkage,d-axis inductance and q-axis inductance are estimated by voltage measuring.The experimental results demonstrate the feasibility of the pro-posed method.
