【Abstract】 This paper proposes a novel discrete fuzzy sliding mode control scheme for high accuracy AC servo system. The controller is very easily designed and the sliding condition is easily satisfied . The system with this controller has good robustness, and the chattering on the slide module is apparently decreased. Simulation results show that AC system with the novel discrete fuzzy sliding mode control is insensitive to parameter variations and disturbances and has good fastness.更多还原
