一种新的模糊内模预估控制器

A NEW CONTROLLER OF THE PREDICTIVE CONTROL METHOD OF FUZZY INTERNAL MODEL

采用内部模型控制、模糊预估器和模糊控制器相结合 ,对模糊内模预估控制方法进行了研究。其方法是利用模糊预估控制器克服时滞 ,通过对具有纯滞后的被控过程进行的数字仿真研究 ,结果表明 :这项研究的控制效果要优于常规 PID控制、模糊控制 (Fuzzy)和内模控制 (IMC)

A predictive control method of fuzzy internal model is proposed. It adopts internal model control, fuzzy predictor and fuzzy controller which are combined together to act on the controlled process. This method utilizes fuzzy predictive controller to cope with dead time. The results of computer simulation show that the method can reduce the static error of system and enhance the robustness as well as disturbance rejection ability.Results show that this method is superior to other controllers such as PID, MIC and Fuzzy control.
