摘要：AbstractThe control of the curvature and the contact force at the strip-roll contact point of a metal strip in an experimental device is investigated. For this purpose, a material model and a steady state strip deformation model are derived. Using these models, feasible combinations of curvature and contact force are computed. A control structure is proposed that comprises a feed forward and a feedback part. Exponential stability of the closed-loop system is shown. Results from a numerical example verify the robustness of the controller against model-plant mismatches and its suitability for disturbance rejection.
