Abstract: Sensorless control system for permanent magnet synchronous motor (PMSM) has been widely used in many areas for its simple installing and easy realizing advantages. This paper mainly analysed sensorless control system of PMSM, estimated the angel of rotor and speed based on flux observation initially, PLL and state observer were used to obtain the accurate angle. Used Simulation toolbox design of Matlab to implement the simulation of control system and analyzed the simulation results. The results verified the correctness and feasibility flux observation method that used in paper. Key words: PMSM;sensorless;flux observation;PLL;state observation;simulink |
