Abstract

Un sistema de colada de rodillo gemelo donde los rodillos de colada tienen una pinzada entre los rodillos de colada, cada rodillo teniendo una circunferencia y un periodo rotativo. El controlador de rodillo de colada ajusta la pinza entre los rodillos de pinzada en respuesta a señales de control. El sensor mide al menos un parámetro de la banda de colada. El controlador ILC recibe las señales de medición de banda desde el sensor y proporciona señales de control al controlador de rodillo de colada. El controlador ILC incluye un algoritmo de control ILC para generar las señales de control con base en las señales de medición de banda y un estimado de retraso de tiempo basado en la circunferencia, periodo de rotación, y una longitud de la banda de colada entre la pinzada y el sensor para compensar un tiempo transcurrido desde que la banda de colada sale de la pinzada hasta ser medido por el sensor de banda de colada.
