摘要: 寬帶鋼熱連軋過程中,板形控制和板厚控制本質上都是對軋制過程中有載輥縫的控制,因此兩者各自的控制回路必然存在著相互耦合的關系,這種耦合關系嚴重影響熱軋寬帶鋼板形板厚綜合質量的提高.本文在建立板形板厚耦合模型的基礎上,采用反饋解耦控制方法,實現了板形板厚的解耦控制.計算機仿真結果表明,解耦控制環節的引入,基本消除板厚控制和板形控制之間的影響,尤其是消除輥縫調節對板凸度的連帶干擾,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.
