Title:
METHOD AND DEVICE FOR MEASURING AND/OR CONTROLLING FLATNESS AND FLATNESS CONTROL SYSTEM
Document Type and Number:
Japanese Patent JP2002153909
Kind Code:
A
Abstract:
To provide a method for measuring and/or controlling flatness when a strip is rolled.
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.
