Research And Realization Of Fuzzy Control Technology In Monitor And Control System

Traditional hardware structure of automation processing control system in industry lacks opening. With the development of information and embed technology, an opening distributed control system is needed. This system not only monitors the production processing, but also provides convenient condition to connect the information system. Along with competition of global market and development of computer network technology, great corporations in the world invest more to perfect their enterprise manage-control system. An opening distributed control system will strengthen capability of market competition and accelerate the enterprise development. Enterprise will get higher profit from excellent intelligent control.Fuzzy control has been used in industry for a long time. The improvement of communication speed of field device has made it possible use fuzzy control in the field directly.PID was the main control mode in processing industry, and was fit for certain model control system. For those uncertain model control system and with control experience or rules, fuzzy control is the best choice. Fuzzy control can respond rapidly.A lot of work has been done in research and improvement of fuzzy control theory. At present, Fuzzy control is mainly realized in PLC directly, Realization of fuzzy or other intelligence control strategy in Man-Machine Interface software make it convenience to adjust control arithmetic to improve performance of process control.This subject was developed on an opening distributed control system -ARICON(Developed by the Design and Research Institute of Metallurgical Automation ), methods were introduced to add fuzzy control functions in configuration software-ARJTECT. Similarly, model identifying, neural network and other arithmetic can be used in it too.
