摘要
典型模糊控制器在难于建立数学模型或对控制精度要求不高的场合已得到了成功的应用．但与传统的控制方法相比，它存在两个明显的弱点，一是所得到的模糊控制规则不能保证其是最优的或是次最优的，二是在设计模糊控制器获取模糊控制规则时主要是凭经验进行，没有系统的步骤可遵循．本文提出了一类最优模糊控制器的系统设计方法及步骤．这种最优模糊控制器既有典型模糊控制器的形式，又有类似于线性二次型的性能指标，使该性能指标趋于最小，便能保证所得到的模糊控制规则最优．采用该最优模糊控制器的造纸机计算机控制系统成功地投入实际应用，效果令人满意．
The fuzzy logic controller has been shown its power in ill-defined or nonprecise systems.However there are still some shortcomings.Two of them are that the control rules of fuzzy controller could not ho always made optimal and that no systematic method is available for acquiring fuzzy control rules.In this paper,a systematic design procedure of an optimal fuzzy controller is presented.This controller will have the form of an ordinary fuzzy controller and make the fuzzy performance index minimum,which is similar to the quadratic performance index.This method is applied to a papermachine control system and the control result is very satisfsctory.
