英文摘要:

      For the speed tracking control problem of the PMSM servo system,the saturation function is introduced to reduce the chattering phenomenon,one controller under uncertain environments is proposed.In the design of the controller,RBF network is used to approximate adaptively the uncertainty,while the backstepping method and the idea of sliding mode control are cited to design the controller.Theoretical analysis demonstrates that the controller can ensure the system Lyapunov stability.Numerical experiments show that the controlled system can effectively suppress uncertainty disturbance.The speed output can track the reference signal.
