  • This paper proposed a flatness feed-forward control method based on the on-line measured data of strip profiles at the entrance and constructed a flatness predictive control model for tandem cold rolling mills, the correctness of which was verified by comparing with actual values. On the base of studies on the flatness feed-forward control strategy and the flatness feed-forward control model, a complete set of flatness feed-forward control models and the corresponding off-line simulation system were established for a 1550UCMW tandem cold rolling mill equipped with a profile instrument at the entrance. Simulation results showed that when the flatness feed-forward control model was used, finishing strip flatness fluctuation caused by the variation of incoming strip profiles weakened obviously, leading to further improvement in the quality of finishing strip flatness.
