基于增强型高阶广义积分器磁链观测器的永磁同步电机无位置传感器控制策略

In the position sensorless control area of permanent magnet synchronous motor (PMSM), compared with back electromotive force method, the flux observer can realize a wider operating range because it is decoupled from speed. However, the traditional flux observer will bring about both dc bias problems caused by voltage or current detection error, and harmonics problems caused by converter nonlineari...
