The present disclosure relates to a method for tuning flatness control for rolling a strip in a mill comprising rolls controllable by means of a plurality of actuators, which mill is modeled by means of a mill matrix. The method comprises: a) obtaining an equivalent movement range for each actuator, b) determining a scaled mill matrix by scaling the mill matrix based on the equivalent movement ranges, and c) obtaining a singular value decomposition of the scaled mill matrix for providing flatness control of the strip by means of the actuators. A computer program and a control system for carrying out the above method are also presented herein. |
