一种基于矢量重构的永磁同步电机驱动电流测量误差自适应频率谐波抑制策略

The errors of gain and offset caused by the current sensor measurement can lead to the first and second harmonics in dq-axis currents of the permanent magnet synchronous motor (PMSM) drives. An adaptive-frequency harmonic suppression strategy based on the vector reconstruction for current measurement error is proposed. The dq-axis current vector is recoordinate transformed using the division-frequ...
