Research Of Self-tune Rule Of Fuzzy Control System About Industrial Boiler Based On Fieldbus

High reliability,openness,econmics and industrialize become the urgent requirements of contemporaneity industry control system,this article first looks back to and summarize the history of computer control system and field-bus control system. This article continues to introduces a self-tuning fuzzy control system about industrial boiler,which can self-tune rule of fuzzy controller,This fuzzy control system is based upon field-bus of DeviceNet. After that, this article gives prominence to the advantages of the field-bus products from Rockwell Automation and how to concretely realize the industrial boiler control system that is based upon field-bus. After that,this article detailedly discusses the mechanism and how to come true self-tuning adjustable fuzzy controller. Then, we design self-tuning adjustable fuzzy controller which can self-tune on-line the parameter of fuzzy controller. finally,we realize the adjustable controller in SIMULINK,and take the advantage of OPC(OLE for Process Control)mechanism of MATLAB,to realize the real-time control of temperature of water in the boiler.The control result shows that this controller algorithm has best control performance,and improve the control effect to great extent.
