Research And Application Of Self-Tuning Fuzzy Controller

Because complex industry object has non-linearity, uncertainty and time-change, this paper puts forward self-tuning gene fuzzy controlling arithmetic and self-tuning fuzzy PID controlling arithmetic to satisfy demand of these complex industry processes. Because fuzzy control do not need to know accurate mathematic model of object, but is based on human thinking and producing experience; and because it applies language rule to describe controlling process and bases rule to modify the controlling arithmetic and parameter, at the same time these two mathematic has self-adaptability, they will realize production process control.This paper researches self-tuning gene fuzzy controller arithmetic and self-tuning fuzzy PID controller arithmetic. The result of research shows that these two arithmetic is realizable and have good effect; Make these two arithmetic's ActiveX controllers and increment PID arithmetic ActiveX controller by VB6.0 and VC++6.0, and add them in configuration software; Write DDE program to realize communication with configuration software; Realize control of experimental equipment by these arithmetic controllers and DDE program. The result shows that self-tuning gene fuzzy controlling arithmetic and self-tuning fuzzy PID controlling arithmetic will have good developing foreground and be widely used in industrial control.
