A scheme of fractional order sliding mode speed controller based on fractional order integral sign function is proposed for dealing with the contradiction of the reaching speed and the chattering phenomenon in traditional sliding mode control for permanent magnet synchronous motor (PMSM). Adding the fractional order calculus to the reaching law design can largely increase the response speed on the premise of smaller chattering. The simulation and experiment results demonstrate that the proposed fractional order sliding mode controller not only achieves a faster response speed, but also has a better tracking performance than traditional sliding mode controller. And it also has a good performance of resisting the external disturbance.
