Abstract: To solve the chattering problem of traditional sliding mode observer in the permanent magnet synchronous motor (PMSM )sensorless vector control system, this paper proposed a new improved sliding [JP3]mode observer based on a nonlinear energy function reference model.On the basis of the analysis of nonlinear[JP] energy function reference model, an improved sliding mode observer was designed, and the model of PMSM sensorless vector control system based on the improved sliding mode observer was established. At the same time using simulink simulation platform, the simulation test has proved the feasibility of the improved sliding mode observer based sensorless vector control system.
