摘要
通过采用直流伏安法辨识电机定子电阻参数,采用高频注入法和脉冲电压法辨识电机定子电感参数,并对电感参数的2种辨识方法进行了分析和比较,分析永磁同步电机的数学模型,推导出了离线辨识永磁体磁链方法。仿真和试验结果验证了离线辨识定子电阻、定子电感和永磁体磁链方法的有效性。
DC volt-ampere method was used to identify stator resistance,and high-frequency injection method and pulse voltage method were used to identify stator inductance of PMSM.The two identification inductance methods were analyzed and compared,and with the PMSM mathematical model,the off-line calculation of permanent magnet flux linkage was derived.Simulation and experiment result showed that off-line identify stator resistance,stator inductance and permanent magnet flux linkage was effective.
