Abstract: Based on the mathematics model of permanent magnet synchronous motor,proposed a sliding mode observer(SMO)for estimating the position and speed of PMSM.SMO algorithm is simple in structure and easy to be implemented by using a computer.A field oriented control system is achieved by using the observer.Experimental results show that the observer is able to observe the position of the rotor and has good robustness. Key Words: Permanent magnet synchronous motor;Sliding mode observer;Sensorless;Vector control;Experiment
