Strip Thickness Control of Cold Rolling Mill with Roll In rolling mill, the accuracy and quality of the strip exit thickness are very important factors. To realize high accuracy in the strip exit thickness, the Automatic Gauge Control (AGC) system is used. Because of roll eccentricity in backup rolls, the exit thickness deviates periodically. In this paper, we design PI controller in outer loop for the strip exit thickness while PD controller isRoll in Hot and Cold Rolling Mills STLERoll Cooling in Novelis Aluminum Hot and Cold Rolling Mills PRESENTED BY ANDREW HOBBIS Acknowledgement: The work of many former and current colleagues in
