Method and Application of Fuzzy-expert Control System in Coke-oven for Gas Collector Pressure

Based on the collector pressure system of coke-oven which is strongly coupled and disturbed,non-linear multi-variable system,a fuzzy-expert control method is presented.The pressure auto-controller of the second new coke is introduced in detail.It is a hybrid intelligent control approach which incorporates fuzzy control with feed-forward control and expert control.It integrates simplicity,reliability,flexibility and rapidity in restraining disturbance by making full use of each method's advantages.Practical results show that when the outer factors cause the pressure fluctuant,the system can make it stable in the technics area through tuning up the papilionaceous-valve in 30 second.
