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