Abstract

L'invention concerne un procédé et un système de commande permettant de commander un séparateur électrostatique (22). On commande ledit séparateur par sélection d'une valeur de point de réglage pour la qualité de l'un de ses flux de produits; on mesure spectroscopiquement la qualité de ce flux de produits et on utilise un simple contrôleur pour régler automatiquement l'une des variables de commande du séparateur (22) afin de maintenir la qualité de l'un des flux de produits à la valeur de point de réglage. On règle manuellement une seconde variable de commande, une commande automatique pouvant régler la première variable de commande afin de maintenir la qualité de sortie à la valeur de point de réglage. On surveille manuellement le rendement, la seconde variable de commande étant réglée manuellement afin d'optimiser le rendement tout en conservant la valeur de point de réglage.
