| 摘 要： | 针对板带热连轧机活套高度和张力控制系统，给出一种新的多变量解耦控制策略．利用特征传递函数的轨迹来判定闭环系统的稳定性．利用失配角度曲线来检验系统的关联性．采用特征轨迹方法设计出的解耦控制器在最大程度上减弱了活套高度和张力控制系统的关联．最后，用Matlab中的系统仿真工具箱Simulink对活套多变量控制系统进行仿真实验，结果表明解耦后的活套控制系统可获得更好的控制性能．

| Abstract: | A new multivariable decoupling control strategy is developed for looper height and tension control system of hot strip finishing mills.The stability of the closed-loop system is determined by the locus of characteristic transfer function.Also,coupling degree among the variables is determined by the angle misalignment curve.Using the controller designed with the characteristic locus method,the coupling degree between looper height and tension control system is reduced farthest.Finally,simulation results obtained with the Simulink toolbox of the Matlab language show that the decoupled multivariable control system has better performance. |
