基于反电动势的永磁同步电机离散时间转子位置偏差补偿方法

In permanent magnet synchronous motor (PMSM) drives, the rotor position signal is critical. However, the failure of the mechanical position sensor and the position tracking error of the resolver-to-digital conversion causes position signal biases. These position biases significantly deteriorate motor drive performance, whereas there are few effective methods to handle both biases simultaneously. T...
