Coiling temperature control of hot steel strip using combined feedforward, feedback and adaptive algorithms

In a hot steel strip production line, the coiling temperature control is critical for strip quality. In this paper, the coiling temperature control of a typical steel strip mill is investigated. A simplified dynamic model is introduced, based on which a cooling control scheme with combined feedforward, feedback and adaptive algorithms is developed. Simulations with a more accurate model validated using actual plant data are conducted, and the results have confirmed the effectiveness of the proposed control method
