Temperature Predictive Fuzzy Control of Coke Oven

On the basis of analyzing production characteristics of coke oven, heating intelligent control model of coke oven was built. Then predictive fuzzy control algorithm was proposed combining predictive control with fuzzy control. In the algorithm, predictive control was responsible for control accuracy and fuzzy control was to provide control variables when predictive model was not convergent as well as uncorrected control variables when the model had converged. A good temperature control of coke oven with characteristics of large inertia and time delay was obtained by application of the algorithm. The practical running indicates that the algorithm has good control performance and great practical value.
