Study on Sensorless Control of Saliency PMSMs Based on MRAS

摘要：

A speed observer based on MRAS is proposed ,and is used to realize sensorless control in a saliency P1MSM drive system .The outputs of reference model and adjustable model are compared in an adaptation mechanism,and the adaptive laws of rotor speed is obtained by Popov stability thory. The simulation results show that the proposed speed observer is capable of estimating speed effectively .and the orientation control system has good dynamic and static performances.
