In order to improve the stability, anti-interference and robustness of surface permanent magnet synchronous motor ( SPMSM) , the mathematical model of surface permanent magnet synchronous motor was established based on PCHD theory. The speed adjustment and estimation algorithm of surface permanent magnet synchronous motor were proposed on the basis of sliding mode control theory. And the speed sliding mode controller was designed. The motor speed was estimated by a sliding mode observer. Finally simulation experiments were carried out by using MATLAB. The simulation results showed that the actual speed and estimated speed could fit well and the speed tracking performance was better. This speed set and estimated strategy of control system had good anti-interference performance.
