Resumo: This paper presents a control strategy to regulate the molten steel level of a strip-casting process. The molten steel level may be controlled using the roll gap, the tundish output flow or the roll rotation speed as control inputs. To improve the strip thickness uniformity the molten steel level we propose the use of the roll rotation speed as the control input assuming the tundish output flow is regulated in a previous stage. To regulate the molten steel level, conventional PI and feedback linearizing controllers with compensation for modeling errors are considered. Simulation results are presented considering the real system parameters.
