Abstract
L'invention porte sur un procédé de commande d'une section de raffinage thermomécanique de pâte (TMP). La section de traitement comporte au moins un premier raffineur comportant une pluralité de capteurs disposés dans une position prédéterminée sur une plaque de raffineur de l'au moins un premier raffineur. Le procédé comprend la mesure ou différemment l'estimation d'une ou plusieurs variables de traitement représentant des états externes à l'extérieur du raffineur, selon la formule (I) pour ladite section de traitement et la mesure ou différemment l'estimation d'une ou plusieurs valeurs représentant un ou plusieurs états internes, selon la formule (II) à l'intérieur dudit au moins un premier raffineur, et le calcul d'une modification pour ladite au moins une variable manipulée (u 1) pour ledit au moins un raffineur à l'aide de ladite mesure d'un état interne selon la formule (II) dudit au moins un raffineur, et une mesure desdits au moins un état externe de traitement selon la formule (I), pour ladite section de traitement à l'aide d'un modèle de traitement mathématique.
