Modeling and Control of Bimodal Coiler System

Abstract

The coiler system is a final part of hot rolling process. The torque of the mandrel and the force imposed on the pinch roll are cooperatively controlled in order to suppress the tension fluctuation when the steel plate leaves the final stand. In this paper, the coiler system is modeled as a bimodal hybrid system, and two control methods are applied. The effectiveness of the proposed methods are evaluated by simulation.
