Start-up control of a hot strip mill tension/looper system: an approach based on model predictive control

Tension and looper control is the key to successful operations in the hot strip finishing mill and the various control strategies have been applied to improve the performance of the transient. In this talk, we focus on an off-line control design method of the tension and looper system and derive a start-up control law based on model predictive control. By employing a multi-parametric programming method for the posed problem, a nonlinear feedback control law, which is equivalent to the model predictive control, is constructively given. The feature of resulting control system is illustrated with numerical examples.
