Application of fuzzy theory on gas collector control

Fuzzy control technology is a practical alternative for the nonlinear, big inertia and big hysteresis plant. In industrial production, the pressure of coke oven gas collector is nonlinear and has more strong couple property change parameter essentially. It is highly impossible to describe the course that it changes with general mathematics model. Relying on the traditional PID regulation technology is hard to take effective. This paper gives a kind of cokeries gas collector pressure control scheme based on fuzzy control theory. With the use of fuzzy control system, we are not only obtaining improved steady pressure, but also alleviating the pollution level in certain scope.
