Coke oven production possesses the characteristics of nonlinear, large inertia, large disturbances, and highly-coup ling and so on. According to the characteristics of coke oven production process and control demand of coke oven production, intelligent control structure and models of coke oven production process was conducted. Firstly the intelligent control structure of coke oven production process was established. Then coal blending intelligent control, gas collector pressure intelligent control and combustion intelligent control of coke oven were discussed simply, while heating intelligent control, the production plan and schedule were discussed in detail. The control principle of combining the intermittent heating control with the heating gas flow adjustment was adopted, and fuzzy hybrid control was proposed to establish heating intelligent control strategy and model of coke oven, which combined feedback control, feed forward control and fuzzy intelligent control. The production plan and schedule of coke oven were optimized by utilizing the dynamic program and genetic algorithm. The practical running indicates that the system can effectively improve quality of coke and decrease energy consumption.
