ON THE POSSIBILITY OF LOOPERLESS ROLLING ON HOT ROLLING PROCESS

摘要

We discuss the possibility of looperless control at finishing mill of hot rolling process in this paper. In recent years, the precision of thickness and width of hot coil is becoming more and more strict. So we must develop powerful controller which stabilizes the rolling process even if plant parameters are perturbed. It is cleared that performance of control system with the compensator designed by 11 synthesis considering parameter perturbation is better than that with the compensator designed by H_(infinity).
