| 摘 要： | 宽带钢热连轧过程中,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,因此两者各自的控制回路必然存在着相互耦合的关系,这种耦合关系严重影响热轧宽带钢板形板厚综合质量的提高.本文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,解耦控制环节的引入,基本消除板厚控制和板形控制之间的影响,尤其是消除辊缝调节对板凸度的连带干扰,解耦控制效果良好.

| Abstract: | The essence of both automatic shape control (ASC) and automatic gauge control (AGC) is the controlling of loaded gap between rolls, so the closed control loops of ASC and AGC are coupled. The coupling between ASC and AGC holds down improvement of the combined controlling quality of ASC and AGC heavily. After the coupled process control model was developed, a feedback decoupling controller was proposed to decouple the model. The simulation result is perfect and indicates that the cross coupling between ASC and AGC especially the disturbance from AGC to ASC was depressed, which ensures the quality of the decoupling controller. |
