| Abstract: | The reason is analyzed that the performance of the time-delay system controlled by the conventional Smith controller is poor,and the shortages of the conventional fuzzy controller are introduced.So a kind of improved fuzzy-Smith controller that is suitable to the big time-delay system is designed,and GA optimizes its parameters.The simulation results show that the improved fuzzy-Smith controller has good quality characteristic and well robustness. |
