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 estimation utilising an SMO. The study concluded that during a variety of velocity and load conditions, sensorless PMSM control using SMO depending on sigmoid function can predict orientation with extreme precision and prevent chattering. Here, the PMSM speed control algorithm is constructed using SMC.
