Abstract

Regulación, especialmente regulación de ajuste hidráulico, por ejemplo para un bastidor de laminación, que consta de al menos un regulador (9) y al menos un elemento de ajuste (15), siendo alimentados al regulador (9) como magnitudes de entrada un valor teórico y un valor real, en virtud de los cuales el regulador (9) suministra una magnitud de ajuste del regulador para el elemento de ajuste (15),caracterizada porque sobre la magnitud de ajuste del regulador se acopla un valor de control previo, calculando en un circuito de regulación modelo (6) continuamente un valor previsto, esperado en virtud del control previo, para el valor real, alimentando al regulador (9) como valor teórico un valor de guía calculado a partir de este valor previsto.
