摘　　要：结合模糊PID控制与模糊自适应Smith预估控制的优点,提出了模糊Smith智能控制方法。用模糊控制方法设计了改进型Smith预估器的滤波时间常数,并制定了其整定规则和参数的模糊自适应调整机构。仿真研究表明,模糊Smith智能控制能改善参数时变的纯滞后系统的控制性能,提高系统控制时的鲁棒性与自适应性。Based on the advantages of fuzzy PID control and fuzzy adaptive Smith predictor control, a Fuzzy Smith intelligent method is proposed. The filter lime constant of improved-type Smith predictor is designed by fuzzy control method, The self-ttming rules and parameter fuzzy adjust organization are established, Simulation research shows that Smith intelligent control can improve the control pefformance of the pure hysteresis system, and the robustness and adaptability are improved.
