摘要
模糊推理机按照功能的不同可以分为输入模糊化、规则评价及输出反模糊化 3个部分 .它利用专家提供的知识基 ,即隶属函数和控制规则 ,再对实时输入信号进行模糊推理 ,以产生有效的控制信号 .在传统的模糊推理机基础上提出了一种在线模糊推理算法 ,可实时修改隶属函数曲线 ,以提高控制系统的自适应性 .该算法在变频式空调器的温度控制中得到了成功的应用 .
According to the difference of functions,fuzzy reasoning processor is classified as three parts,such as input fuzzification,rule criticism and output defuzzification.It uses knowledge base,i.e.membership functions and control rules,provided by the experts and take fuzzy reasoning to real- time input signals and result in effective control signal.An on- line fuzzy reasoning algorithm is presented basen on the classical fuzzy reasoning.This algorithm can real- time modify membership function curves to enhance the adaptiveness of the control system and successfully applied to the temperature control in the variable- frequency air conditioner.
