摘　　要：针对热连轧活套高度和张力的双输入双输出强耦合系统,文中提出一类基于滚动时域优化原理的多路控制策略.基于滚动优化原理,在每一个周期内,顺序求解子系统的控制律后及时更新系统.从H∞观点出发,将解耦问题转化为干扰抑制和多目标优化问题,能够减轻计算机的负担,提高控制系统的性能.仿真结果证实了该方法具有良好的解耦效果和控制性能.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.
