Systems and methods are disclosed herein that include providing an active torsion damper control system that includes a rotatable component (206) and a rotatable measurement interface (302) disposed on the rotatable component, the rotatable measurement interface having at least one torsional strain gauge configured to measure a strain of the rotatable component, a torque management (306) computer configured to determine a resonant frequency of the rotatable component and a corrective torque needed to be applied to the rotatable component to excite the resonant frequency as a function of the measured strain, and a correction motor (308) configured to impart the corrective torque on the rotatable component. La présente invention concerne des systèmes et des procédés consistant à fournir un système de commande d'amortisseur de torsion active qui comprend un composant rotatif et un interface de mesure rotatif disposé sur le composant rotatif, l'interface de mesure rotatif présentant au moins une jauge de déformation due à la torsion configurée pour mesurer une déformation du composant rotatif, un ordinateur de gestion de couple configuré pour déterminer une fréquence de résonance de l'élément rotatif et un couple de correction devant être appliqué à l'élément rotatif pour exciter la fréquence de résonance en fonction de la déformation mesurée, et un moteur de correction configuré pour transmettre le couple de correction au composant rotatif.
