Fuzzy optimaization control of the temperature for the heating process in coke oven based on co-evolution

Fuzzy control method is often used in the flue temperature control, but it is difficult to get perfect membership function and rule base. To this problem, this paper present a fuzzy control method based on the co-evolution. Through the analysis of the control parameters, two species including the membership parameter specie and fuzzy rule specie are determined in the co-evolution algorithm. Both performance and interpretability of the controller are considered in the fitness function and cooperative strategy of the two species is used to get the membership function and fuzzy rules and design the flue temperature optimization controller. The application shows that the method is effective.
