PROBLEM TO BE SOLVED: To provide a method for measuring and/or controlling flatness when a strip is rolled.;SOLUTION: In the method for measuring and/or controlling the flatness of the strip when rolling is performed, this method has a step for detecting a measured value, a step for breaking down the each measured value into each independent component and a step for controlling each controlled variable. The breakdown of each measured value is performed using an orthogonal polynomial, the each independent component is compared with each target value from a target value-flatness model and control deviation is fed to a multivariable controller through a decoupling part.;COPYRIGHT: (C)2002,JPO
