Abstract :
A nonlinear speed controller for permanent magnet synchronous motor (PMSM) based on backstepping control, sliding mode approach and RBF network was designed. On the one hand, the proposed strategy adopts backstepping to guarantee the control precision. On the other hand, the combined RBF sliding mode method could enhance the robustness compare with conventional sliding mode control. A simulation model for the PMSM control system using the designed controller was built. The simulation results show that the controller can achieve fine speed tracing performance and good robustness against parameter variations and load torque disturbance.
