【Abstract】 Based on the hydraulic AGC modernization project of the Capital Iron and Steel Company 3340mm plate mill, this paper presents the computers system and sensors configuration. The mill stiff model and mill hydraulic cylinder control (HCC) principle and its frequency response performance are given. The lockup AGC and absolute AGC are discussed. At end of this paper, the backup rolls eccentric compensation and oil film compensation and other compensations are presented.更多还原
