摘　　要：通过对带钢张力产生机理的分析,建立了张紧辊带钢张力的动态机理模型和状态空间模型,在此基础上,与传统的带钢张力比例—积分—微分(PID)控制方法不同,采用状态反馈和极点配置方法设计了带钢张力的多变量跟踪控制器.所设计的带钢张力跟踪控制器能够使各个带钢张力的实际值渐近跟踪相应的设定值,可获得良好的控制效果.通过仿真实验证明了本文的带钢张力模型和跟踪控制方法的有效性.By means of the mechanism analysis for the strip tension, the dynamical mechanism model and the state space model of the strip tension of the bridling roll are proposed. Based-on these models, the multivariable tracking controller of the strip tension is designed. The proposed tracking controller is designed using the state feedback and pole assignment method, which is different with the traditional PID controller. The proposed tracking control method of the strip tension can control the actual strip tension to track asymptotically their set-points with the satisfactory performance. Simulation experiments are implemented to illustrate the efficiency of the tension model and multivariable tracking control method.
