Optimal control system of coke oven collector pressure control

The nonlinear PID optimization control scheme is proposed in this paper based on the fact that coke oven gas collector pressure control is multi-variable nonlinear system. This study developed nonlinear intelligent regulator with variable bias dead zone and feed-forward functions use of a variety of advanced control strategies. Then taken DCS to realize optimal control based on the traditional feedback control. Engineering applications show that the system design is universality and effectiveness.
