CA 2401543
The invention relates to a control system, especially one for use in the control of industrial plant such as a polymerisation reactor. In particular, the invention provides a method of controlling a process comprising the steps of: a) generating a first-principle model corresponding to the process; b) inputting data describing the current and desired future process conditions; c) generating a linear approximation to the model which is valid for said current conditions; d) using said linear approximation to determine an approximate solution to a control problem related to the process; and e) controlling the process using said approximate solution.
L'invention concerne un système de commande, notamment un système destiné à commander une installation industrielle, telle qu'un réacteur de polymérisation. D'une manière spécifique, l'invention concerne un procédé permettant de commander un processus et consistant: a) à générer un modèle de premier principe correspondant au processus; b) à introduire des données décrivant les conditions courantes et souhaitées du prochain processus; c) à générer une approximation linéaire au modèle qui soit valable pour lesdites conditions courantes; d) à utiliser ladite approximation linéaire afin de déterminer une solution approximative à un problème de commande relatif au processus; et e) à commander ce processus au moyen d'une solution approximative.
