Application of the Relative Gain Matrix to Combined Shape and Gauge Control System of Hot Strip Mills
-
摘要: 針對板形板厚控制的耦合問題,結合1700 mm熱連軋機實際控制系統,建立了板形板厚耦合控制對象的數學模型.采用Bristol-Shinsky相對增益分析表明,1700 mm熱連軋機的板形板厚耦合效果明顯,嚴重影響高質量帶鋼生產,必須進行解耦設計.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.
