Title (EN) CHANGING SET POINTS IN A RESONANT SYSTEM
(FR) CHANGEMENT DE POINTS DÉFINIS DANS UN SYSTÈME RÉSONNANT
Abstract: front page image
(EN)A method for changing a set point of a system where period of a dominant resonance of the system is determined, a change profile for the set point change is processed; a time period for the set point change based on the period of the dominant resonance in order to minimize excitation of the dominant resonance is also processed; and the set point change is actioned according to the processed change profile and the time period.
(FR)L'invention concerne un procédé de changement d'un point défini d'un système où une période d'une résonance dominante du système est déterminée. Dans le procédé : un profil de changement du point défini est traité ; une heure du changement du point défini basée sur la période de la résonance dominante est également traitée, afin de minimiser l'excitation de la résonance dominante ; et le changement du point défini est exécuté d'après le profil de changement et l'heure traités.
