摘要： The invention concerns a method for regulating flatness of a metal strip at the output of a roll housing comprising flatness regulating means including at least one dynamic flatness actuator, which consists, during the rolling process, in characterizing the flatness of the strip by measuring a quantity D in n points distributed across the width of the strip, from n measurements of the quantity D, then using an action model of flatness regulation on the flatness and an optimizing method, in determining an overall setpoint for the regulating means, said overall setpoint including at least one elementary setpoint for the dynamic actuator, such that a calculated flatness residual defect criterion is minimal, and in executing the overall setpoint with the flatness regulating means. The invention is characterized in that the action model on the flatness used for determining the overall setpoint comprises for the dynamic actuator, as many submodels as there are points for measuring the quantity D characteristic of flatness, each submodel enabling the effect of the dynamic actuator on the quantity D to be calculated at the corresponding point when a setpoint is applied thereto.
