An optimization method of operation parameter based on comprehensive status evaluation model was proposed on the background of optimization control problem for lead-zinc sintering process. Based on the sintering process mechanism analysis, the comprehensive status evaluation model was proposed, which synthesizes a lot of intelligent technique, including principle components analysis, neural network, fuzzy theory and so on. Then according to the current operating parameters and the result of comprehensive status evaluation model, the optimum operation parameters were calculated by using matching optimization algorithm based on fuzzy C-means clustering. The results show that the fluctuation of status can be meliorated efficiently and the output and quality of agglomerate is improved, so the problem of optimization control for lead-zinc sintering process can be resolved.
