Abstract:  A backstepping sliding mode speed controller of permanent magnet synchronous motor (PMSM) was designed under the condition of variable reference velocity and load torque. This controller could improve the PMSM control system dynamic speed tracking effectively by making good use of good static and dynamic characteristics of backstepping algorithm and good robustness of sliding mode algorithm. The simulation and dSPACE experiment results show that the backstepping sliding mode controller has better speed dynamic tracking and stronger robust compared with backstepping controller.
