Abstract

In this paper, a novel sliding mode variable structure observer is presented for estimating the rotor position angle of permanent magnetic synchronous motors to achieve position sensorless vector control. Compared to other traditional observers, the proposed observer can overcome the defect of parameter dependence based on motor mode. Simulation results show that the proposed observer can greatly enhance the stability of the system regardless of parameter variation and load disturbance.
