Start-up Control of a Hot Strip Mill Tension/Looper System: an Approach based on Model Predictive Control

Abstract

For the start-up control of tension and looper system, an off-line design method of the control law is considered based on model predictive control approach. By employing a multi-parametric programming for the posed problem, a piecewise affine state feedback control law, which inherits the advantage of the model predictive control, is constructively given. The feature of resulting control system is illustrated with numerical examples.
