Sensor Less Control of PMSM using SMC and SMO
Abstract: Some particular PMSM applications do not allow for the proper mounting or use of position sensors. A number of PMSM control problems can be resolved with sensorless PMSM control. It is crucial to have a precise predicted position while avoiding the chattering issue for sensorless PMSM control. This paper establishes a prerequisite for a sliding mode observer (SMO) to enter a sliding surface and offers a sigmoid-based algorithm for position …
