Abstract

This paper describes a switching model for cal-ciner outlet temperature via grey correlation analysis, aims to the outlet temperature control of calciner. Firstly, we analyze the cement precalcining process and find quantity of tertiary air, coal feeding and raw material feeding are the influencing factors of calciner outlet temperature. Secondly, we establish an offline mathematical model of calciner outlet temperature based on grey theory, but the fitted value is inaccurate. Then we provide an online switching modeling method, which means the model would change correspondingly to reflect the variation trend of calciner outlet temperature. Finally, the simulation results show the effectiveness of the proposed method.
