Observer Based Speed Control of PMSM Servo Systems

Abstract:

A speed observer which is consisted of the full order state observer and Kalman filter was designed to estimate instantaneous speed in this paper. It utilized full order state observer to obtain load torque and position information, and combining with electromagnetic torque as the input of Kalman filter. Simulation results show that this method can improve the speed detection accuracy of the PMSM servo system.
