【Abstract】 Automation systems for strip rolling mills are continuously being improved for the production of strip with high quality and low scrap loss. It is important to establish a process control system for the combined shape and gauge control system in hot strip rolling. The decoupling network for the multivariable system was designed based on the principle of feedforward compensation by considering the characteristics of the combined system. The decoupling single variable system has the characteristics of main channel of the plant. Considering the decoupling technological parameters of the 1 700 mm hot strip mill at Wuhan Iron and Steel Company, which vary widely with the rolling condition, gain scheduling decoupling control was developed for application in hot rolling. The developed mathematical model with library functions for gain scheduling is introduced and approved to be effective and has been applied in the production mill.更多还原
