Control methodology for stabilized strip tracking in tandem cold strip mill system

This paper presents modified sliding-mode control for the tandem cold strip mill during Flying Gauge Change (FGC) period that is an important component for achieving fast stabilization of strip tracking when FGC period is closed. It means that the proposed algorithm can attenuate strip oscillations generated by inexactitude of setup values of FGC. As such, in real system, we expect to reach a high level of merit in cost aspect. The proposed algorithm is compared to method without proposed algorithm, and the effectiveness is verified through the results of simulation.
