Abstract: A nonlinear speed controller for permanent magnet synchronous(PMSM)based on fuzzy sliding-mode was designed against the effects of the coupling between the current and the speed.The proposed strategy could reduce chattering compare with conventional sliding-mode control.Built a simulation model for PMSM using the designed controller.The simulation results show that the controller can realize the speed tracing,dynamic and static performance and good robustness.
