trol (AGC) methods have been developed for cold mill processes. On the basis of a linearized model of the rolling mill system, in 1996, Hwang and his colleagues [1] propose a thickness controller using an internal mod-el control (IMC) structure which effectively rejects peri-odic disturbances. In 2002, the multivariable AGC is designed using ...

1.Brief Introduction. This 1450mm 20 Hi Reversible Cold Rolling Mill was designed to roll 1.0~3.0mm plain carbon steel, low alloy steel and 200, 300,400 series. stainless steel board into 0.2-1.2mm thick as clients'requirement. The model has flexible rolling process, and it can adapt to changing raw materials.

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 is ...
