Online Identification of Intrinsic Load Current Dependent Position Estimation Error for Sensorless PMSM Drives

Low-speed sensorless control of Permanent Magnet Synchronous Machine (PMSM) faces an intrinsic problem of increased position estimation error with increased load. This phenomenon is due to changed magnetic saliency caused by the load current on the machine side. Therefore, such position estimation e...
