A reverse bump test, for identifying the alignment of a sheetmaking system while the system remains in closed-loop control, includes the following steps: (a) leaving the control system in closed-loop, (b) artificially inserting a step signal on top of the measurement (or setpoint) profile from the scanner, (c) recording the data as the control system moves the actuators to remove the perceived disturbance (or setpoint change), and (d) refining or developing a model from the artificial measurement disturbance (or setpoint change) to the actuator profile. The technique supplies the probing/perturbation signal to the scanner measurement (which is equivalent to supplying the probing/perturbation signal to the setpoint target) rather than inserting bumps via the actuator set points as has been practiced traditionally.

L'invention concerne un essai au choc inversé, destiné à l'identification de l'alignement d'un système de fabrication de feuilles, le système de commande demeurant en circuit fermé, ledit essai comprenant les étapes suivantes : (a) mettre le système de commande en circuit fermé, (b) insérer artificiellement un signal pas à pas sur le haut du profil de mesure (ou point de consigne) par le scanner, (c) enregistrer les données lorsque le système de commande déplace l'actionneur pour supprimer la perturbation perçue (ou le changement du point de consigne), et (d) affinage ou développement d'un modèle, à partir de la perturbation de la mesure artificielle (ou du changement de point de consigne), pour le profil de l'actionneur. La technique procure le signal d'essai/perturbation à la mesure de balayage (ce qui équivaut à fournir le signal d'essai/perturbation à la cible point de consigne), plutôt que d'insérer des chocs via les points de consigne de l'actionneur, comme cela se pratiquait conventionnellement.
