The present invention relates to a method of providing flatness control for rolling a strip in a mill comprising a plurality of rolls controllable by means of actuators. The method comprises the steps of: receiving (S1) flatness measurement data pertaining to a flatness of the strip; determining (S2) a flatness error as a difference between a reference flatness of the strip and the flatness measurement data; determining (S3) 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 (S4) 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. |
