Title (EN) PREEMPTIVE CONSTRAINT CONTROL
(FR) COMMANDE RESTRICTIVE PREEMPTIVE
Abstract:
(EN) A means of controlling a process with a multiplicity of measurements dependent on one process parameter, so that only the most constraining of the measurements manipulates the process in such a way that the performance of each individual controller selected is equivalent to the performance if there was a single controller controlling only one measurement, the most constraining variable. The means of controlling also manipulates the process to prevent a measurement, that is within a process constraint limit, from excessively exceeding that process constraint limit when it is projected that it would do so without the corrective manipulation.
(FR) Un moyen permet de commander un processus caractérisé par une multiplicité de mesures dépendantes d'un paramètre du processus, de sorte que seule la mesure la plus restrictive détermine le processus, la performance de chaque dispositif individuel de commande sélectionné étant équivalente à leur performance dans les cas où seul un dispositif de commande commande une seule mesure, celle de la variable la plus restrictive. Le moyen de commande règle le processus de façon à éviter qu'une mesure à l'intérieur de limites restrictives du processus ne dépasse excessivement ces limites restrictives du processus lorsque des projections montrent qu'elle les dépasserait si un réglage de correction n'était effectué.
