热轧带钢板形板厚综合控制系统的耦合关系

Application of the Relative Gain Matrix to Combined Shape and Gauge Control System of Hot Strip Mills

摘要: 针对板形板厚控制的耦合问题,结合1700 mm热连轧机实际控制系统,建立了板形板厚耦合控制对象的数学模型.采用Bristol-Shinsky相对增益分析表明,1700 mm热连轧机的板形板厚耦合效果明显,严重影响高质量带钢生产,必须进行解耦设计.

Abstract: Mathematical models of 1700mm hot strip mill are developed for couple in combined shape and gauge control system. Computing relative gain matrices of the combined system is to the effect that decoupling control is indispensable for the production of strip with high quality.
