Nonlinear Receding Horizon Control of Thickness and Tension in a Tandem Cold Mill with a Variable Rolling Speed

Abstract

For the precise control of tension and thickness in a tandem cold mill during acceleration and deceleration, we have developed a nonlinear model including the rolling speed as a time-varying parameter. It is demonstrated from simulation results that nonlinear receding horizon control by real-time optimization results in a satisfactory performance for the nonlinear model.
