Abstract
A method of providing flatness control for rolling a strip in a mill including a plurality of rolls controllable by actuators. The method includes the steps of: receiving flatness measurement data pertaining to a flatness of the strip; determining a flatness error as a difference between a reference flatness of the strip and the flatness measurement data; determining an adjusted flatness error based on the flatness error and weights for actuator position combinations which provide a flatness effect below a threshold value; and utilizing the adjusted flatness error for the control units to control the actuators to thereby control the flatness of the strip. A computer program product and a control system for carrying out the above method are also presented herein.
