Abstract

L'invention porte sur un procédé de fabrication d'aluminium dans une cellule électrolytique utilisant le procédé d'électrolyse Hall-Héroult, ledit procédé comprenant les étapes suivantes : la division de ladite cellule en au moins n sous-systèmes ; pour chaque sous-système, l'estimation de la valeur locale d'au moins un paramètre cible ou de sortie sur la base de la valeur de la mesure d'au moins un paramètre d'entrée ; la modification d'au moins un desdits paramètres d'entrée dans la cellule en exerçant une action physique sur la cellule, si au moins une valeur estimée dudit paramètre de sortie, pour au moins un sous-système, est sensiblement différente d'une autre valeur estimée dudit paramètre de sortie pour un autre sous-système.
