| Abstract: | Multiplexed receding horizon control strategy is proposed for looper height and tension double input-output strongly coupled system. Based on receding horizon control theory, after all subsystem controllers are obtained sequentially, the system is updated in time. The decoupling problem is transformed into a problem of combining disturbance rejection and comprehensive optimization based on H∞ control theory, which can lighten computation burden and improve control performance. Simulation results prove the effectiveness of the method in both decoupling effect and control performance. |
