Abstract

On régule les propriétés du papier en modélisant l'effet d'au moins une variable (f¿D?) de la section de sécheur cylindrique du papier sur l'humidité du papier (Moi) et l'effet du flux de pâte (F¿ts?) et/ou de la composition de la pâte et du flux d'agent de rétention (F¿ra?) sur l'humidité du papier (Moi). Grâce à la modélisation, on régule l'humidité du papier (Moi) en commandant simultanément au moins une variable (f¿D?) de la section de sécheur cylindrique de papier, du flux de pâte (F¿ts?) ou du flux d'agent de rétention (F¿ra?).
