Abstract

The precision of profile and thickness is the most important target for wide strip rolling, but the coupling of profile control and thickness control is ignored in rolling schedule, which holds down the simultaneous quality improvement of profile and thickness. A cross-coupled process control model for combined shape and gauge control was developed on the basis of the fact that both controls for profile and thickness are realized by controlling the rolling gap. A dynamic decoupling controller was then proposed to decouple the model. Both the simulation results and the online production data are valid and ensure the quality of the decoupling controller.
