Realizing Principle of the Single-Chip Microcomputer Fuzzy Control Based on the Functioning-Fuzzy-Subset Inference and Its Application

针对CRI模糊推理方法的复杂性 ,首先提出了作用模糊子集推理方法 ;然后将该推理方法与单片机数字运算特点相结合 ,提出了基于作用模糊子集推理的单片机模糊控制实现原理 ,研制开发了 80C5 5 2型单片机模糊控制器 ;最后以建筑热工系统为被控对象 ,试验研究了测试室温度模糊控制过程 .

Aiming at the complexity of the compositional rule of inference (CRI), the functioning fuzzy subset inference (FFSI) has been put forward at first. Then the realizing principle of the single chip microcomputer fuzzy control based on the FFSI been discussed, which has combined the FFSI with the digital operation characteristic of the single chip microcomputer, and the single chip microcomputer fuzzy controller 80C552 has been developed. In the end, the process of the fuzzy control for the temperature indoor has been studied by experiments, by using the building thermal system as the controlled object.
