程度推理与程度控制

Degree Reasoning and Degree Control

文章把语言值规则（模糊规则）视为语言值及其程度（隶属度）之间的一种对应关系，提出了程度函数和程度规则的概念，并由此建立了一种称为程度推理和程度控制的推理与控制方法。采用程度推理和程度控制，传统的模糊推理就变为简单的符号推演和函数计算，传统的模糊控制由数值／（语，度）转换、（语，度）变换和（语，度）／数值转换等三步来实现。

In this paper,the language value rule(fuzzy rule) is looked on as a corresponding relation between language values and their degree. Thus,two concepts of degree function and degree rule are presented. And a new method of reasoning and control is established. The method of reasoning and control is called degree reasoning and degree control. If using the method of degree reasoning and degree control,then the traditon fuzzy reasoning changed into simple symbolic inference and functional compute,and the trandition fuzzy control is realized by three steps: number/language value,degree) conversion, (language value,degree) transformation and (language value,degree)/number conversion.
