A predictive control strategy for burn-through point in sintering process

This paper presents a predictive control strategy named as generalized predictive control with closed-loop model identification for burn-through point (BTP) in sintering process. The closed-loop model identification method describes the dynamic characteristics of sintering process. Based on the model, the BTP generalized predictive control model predicts BTP accurately and computes the strand velocity. A BTP control system is established and implemented in an iron and steel plant. The running results show that the system effectively guarantees the stability of sintering process, sufficiently suppresses the fluctuation of BTP, and greatly increases the quantity and quality of sinters.
