Abstract

This paper presents decentralized control application for stabilization of strip tension in Hot Strip Finishing Mill. Hot Strip Mill, in particular, thickness deviation at head-end and tail-end becomes more serious problem. In order to stabilize strip tension, feedforward decentralized control system has been proposed with the high performance of automatic gage control system. This control method has been confirmed effectiveness by simulations and applying in hot strip mill has shown thickness improvement.
