摘　　要：设计了一种基于偏差和偏差变化率的模糊规则切换Fuzzy-PID双模控制器,避免了传统Fuzzy-PID双模控制阈值切换是由程序自动进行切换,而存在的阈值如何选取及切换扰动等问题.给出了本控制器的控制性能,如鲁棒性、跟踪性和抗干扰能力与PID和常规Fuzzy-PID双模控制的仿真比较.The common Fuzzy -PID control is switched based on threshold value by program. Therefore, how to select suitable threshold value and existing disturbance during switching are defeats unavoided. However a new Fuzzy - PID double model controller with fuzzy rules switching based on error and one - level error difference proposed in this thesis can resolve the problems. Finally its control performances i. e. , robustness, tracking, the ca- pacity of the anti - interference, are compared with those of PID and the common Fuzzy - PID control by simulation.
