基于改进型多复系数滤波器的永磁同步电机驱动电流测量误差补偿

Current measurement errors (CMEs) including offset and gain errors can lead to the first- and second-order harmonics in dq-axes currents of permanent magnet synchronous machine (PMSM) drives. The thermal drift-caused CME can change during the operation of the PMSM, which should be compensated online. This article proposed a CME online compensation strategy based on a modified multiple complex-coef...
