| 摘 要： | 针对于燥系统具有不确定特性、大滞后的特点，提出了一种将模糊PID与模糊Smith预估器相结合的控制策略，实现了PID参数和Smith预估器滤波时间常数的在线整定，获得了比模糊PID控制、模糊Smith预估器控制更好的控制效果。仿真结果也证明了这一点．

| Abstract: | An improved method that combined Fuzzy PID control and Fuzzy Smith predictor control for the system with uncertainty and long time delay is presented,the on line adjustments of the PID parameter and Smith predictor's filter time parameter are realized.Simulation results show that the proposed scheme has better performance than Fuzzy PID control and Fuzzy Smith predictor control methods. |
