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 ...
