GA1-3R-6940 METHOD AND SYSTEM FOR GENERATING AN ECCENTRICITY COMPENSATION SIGNAL FOR GAUGE CONTROL OR POSITION CONTROL OF A ROLLING MILL Abstract of the Disclosure 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 in- cludes creating a signal F generally corresponding to force FO created by the device and the force FECC caused by eccen- tricity 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 eccen- tricity force FECC, 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 (µ) 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.
