Position Sensorless Control for Permanent Magnet Synchronous Motor Based on Sliding Mode Observer

A position sensorless control method based on the principle of sliding mode variable structure control is presented in this paper. A control strategy of position sensorless for permanent magnet synchronous motor （PMSM）is proposed by means of the analysis of PMSM＇s model and the application of the principle of sliding mode variable structure control, h uses stator current and DC bus voltage which are easily obtained in motor, and rotor position is estimated through sliding mode variable structure control principle. The system has been simulated by using Matlab/Simulink software and the simulation results show that the estimated value of the rotor position is basically consistent with the actual location value.
