Abstract :
Though sliding mode variable structure controller has good robustness and high stability, its chattering phenomenon is widely exist. A fuzzy variable structure controller is designed based on exponential reaching law by combining variable structure control and fuzzy theory. The computer simulation is applied to verify the advance of the fuzzy variable structure controller and the controller is applied to ship course control. The simulation results demonstrate the validity, satisfactory adaptation and robustness of the presented controller.
