In the commertial utilization of sheets produced by cold rolling, it is desirable that the gauge of the material be as uniform as possible and the shape defects are minimum. Flatness of cold rolled products is important when they are used in some fields such as rocket engine casings and other aerospace hardware. A steady state multivariable control scheme is presented in the paper aiming at controlling the minimum and maximum thicknesses of the rolled sheets against any disturbance. Required models are derived in general form and the model gain coefficients are obtained for the cold rolling line of the Egyptian Iron and Steel Company. The paper presents the different ways of applying the proposed control scheme including simple manual method suitable for the developed countries.
