摘　　要：分析了采用常规Sm ith预估器的大纯滞后系统控制性能不佳的原因以及常规模糊控制的不足,研究一种适合大纯滞后系统的改进的模糊Sm ith控制器,并用遗传算法对其参数进行寻优。仿真实验表明,改进的模糊Sm ith控制器具有很好的品质特性和良好的鲁棒性。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 pa- rameters. The simulation results show that the improved fuzzy-Smith controller has good quality characteristic and well robustness
