Abstract
A system and method for adjusting the device used to exert a force against a strip being rolled by a rolling mill having at least one rotating backup roll. This system and method includes creating a signal F generally corresponding to force F.sub.O created by the device and the force F.sub.ECC caused by eccentricity and other variables in phase with the rotation of the backup roll, constructing an analog signal corresponding to the eccentricity signal by using an adaptive digital filter having a first digital input generally corresponding to the eccentricity force F.sub.ECC, a second input correlated with the rotation of the backup roll and a coefficient adjusting algorithm responsive to the first input and a preselected convergence factor (.mu.) and a correlated signal with an incremented value correlated with and driven by the rotation of the backup roll and adjusting the force exerting device by this constructed analog signal.
