Method and device for controlling and regulating of an industrial unit using a closed loop identification phase of its operating parameters
The method involves carrying out initialization stage in which identification software generates a model used by a linear multi-variable predictive monitor (MVAC). Variations of input variables e.g. industrial unit feed rate (MV1) are validated. Unit responses are generated and parameters are genera...

Zusammenfassung: | The method involves carrying out initialization stage in which identification software generates a model used by a linear multi-variable predictive monitor (MVAC). Variations of input variables e.g. industrial unit feed rate (MV1) are validated. Unit responses are generated and parameters are generated. Precision of the model is evaluated, where the software implements the calculation of precision of the parameters from a criterion that decides starting of iteration from generation of parameters when imprecision starts from disruptions of unit operation during the application of variations.
La présente invention décrit un nouveau procédé de contrôle et régulation d'une unité industrielle comportant une phase d'identification en boucle fermée des paramètres d'un modèle de ladite unité industrielle, mise en oeuvre dans un contrôleur linéaire prédictif multivariable (MVAC), ladite phase d'identification étant réalisée en boucle fermée ce qui permet de minimiser la production hors spécification de ladite unité. |
