【Abstract】 A modified fuzzy Smith controller for time_delay system is proposed. It reduces limitation of the accuracy of the model and guarantees the robustness to the variation of the model parameter and disturbance, moreover, the precision of the fuzzy controller is increased .The results of simulation show its availability and applicability for time-delay control system.更多还原
