摘　　要：宽带钢连轧过程中，板形控制和板厚控制本质上都是对轧制过程中有载辊缝的控制，因此存在着耦合关系，严重影响了宽带钢轧制板形板厚综合质量的提高。在建立板形板厚耦合模型的基础上，采用反馈解耦控制方法，实现了板形板厚的解耦控制。计算机仿真结果表明，解耦控制效果良好，达到解耦的目的。In the rolling process of the wide strip, the essential of the shape and gauge control is the controlling of the rolling gap, which indicates the coupling relationship between shape control and gauge control. Thereby, this could seriously affect the promotion of rolling quality in both shape and gauge. Based on the coupled-process model, the feedback-decoupling control is implemented in realizing the combined shape and gauge control. The simulation results indicate that the decoupling is as good as to meet the aim.
