摘要
分析了传统模糊控制稳态精度差的缺陷，引入了智能积分以减少稳态误差和避免积分饱和，采用△ｕ＝ｆ（ｅ，ｅｃ）＋Ｅｄｔ（当Ｅ·ｃ＞０或ｃ＝０而Ｅ≠０）及△ｕ＝ｆ（ｅ，ｅｃ）（当Ｅ·ｃ＜０或Ｅ＝０）（其中ｅ为系统误差，ｃ为系统误差变化，ｆ（ｅ，ｅｃ）为模糊控制器输邮，ＫＫＥｄｔ为智能积分输出，△ｕ。为模糊控制器总输出）。然后设计了一个自组织模糊逻辑控制器以实现快速响应和小的超调，在金属镁还原炉上运行后获得较理想的效果。
This paper analyses the defects of traditional fuzzy control intelligent integral to 'reduce the static errors and avoid integral saturation. Given formulas as follows:△u=f(e,ec)+ K Edt(if E.c> 0 or c=0 E≠0)and △u =f(e,ec) (if E.c<0 or E=0)[Where e issystems error,c is change of systems erros,f(e,ec) are outputs of Fuzzy controller, K Edt are outputs of intelligent integral,△u are all outputs of Fuzzy controller].Finally a SOFLC is designed to realize fast reaction and small overshoot'Applied in Mg- restoring oven satisfsctory result is obtained.
