轨道交通永磁同步电机弱磁区参数补偿

This article proposes a dual-parameters compensation control method to improve the torque accuracy of permanent magnet synchronous motor (PMSM) in flux-weakening region for rail transit. For the sake of the feature that six-step operation is the essential operation of rail transit and switching frequency is very low, the proposed method works on the single q-axis current regulator-variable voltage...
