Chattering suppression of the sliding mode observer for marine electric propulsion motor based on piecewise power function

Chattering suppression of the sliding mode observer for marine electric propulsion motor based on piecewise power function

The sliding mode observer (SMO)–based sensorless control is essentially a discontinuous switching control algorithm. Therefore, there is large speed or torque chattering in the permanent magnet synchronous motor (PMSM) with existing sliding mode observer–based control methods. In order to solve this...
