摘要： 对于具有非线性、强耦合、不确定特性的液压活套系统的多变量控制一直是轧制控制领域的难点问题，为了进一步提高热连轧带钢的控制品质，首先利用ADAMS建立了液压活套虚拟样机模型，然后利用MATLAB设计了一种基于互不相关解耦策略的液压活套迭代学习控制系统，利用ADAMS/Sub模块与MATLAB/Simulink接口得到联合仿真模型.基于此模型，对传统PID控制系统与所设计的控制系统进行了仿真研究，仿真结果表明所设计的控制系统可以更好地减弱活套张力与高度系统的耦合作用，使活套控制系统获得更好的控制效果.

Abstract: The multivariable control for hydraulic looper system which has the features of nonlinearity， strong coupling and uncertainty is the difficult point in the rolling control field. In order to improve the control performance of hot continuous rolling strips， a virtual prototype model of the hydraulic looper was built by using ADAMS， then the iterative learning control(ILC)system based on a non-interactive decoupling strategy was designed by using MATLAB， thus a co-simulation model was built by using ADAMS/Sub module and MATLAB/Simulink interface. Simulation studies were made for traditional PID control system and for the designed control system on the basis of this co-simulation model.The simulation results showed that the designed control system further weakens the coupling effect between the looper height and tension， and achives better control effect of the looper system.
