According to the characteristics of foil rolling process and the instrument configuration, a set of automatic gauge control (AGC) system for aluminum foil rolling mill was designed. The control principle of every control method was given. The Smith predictor and variable gain were used to reduce the effect of pure delay on the control system. And the decoupling compensation for other control link was implemented. The tension adaptive control scheme was given according to the tension oscillating problem, and the variable acceleration control in rolling speed AGC was proposed. In order to avoid the spillover phenomena of single controller, the thickness optimization control was implemented by using main controller and optimize controller. For the maximal production, the rolling speed maximization control and target thickness adaptive control were brought forward. Application results indicated that the system shows good control effect.
