Much research has been done about Automatic Gage Control for cold rolling mill of steel, but universal study for cold rolling mill control has not been shown yet. The purpose of this paper is to show the fundamental control law for gage and tension control of cold rolling mill, based on general description of cold rolling process characteristics. We formulate and analyze the process dynamics considering the structure. The decoupling compensator is generally expressed, and the effect is shown. ILQ control law is recommended for mill entry process.
