Title (EN) SYSTEMS AND METHODS FOR ACTIVE DAMPING OF A MOTOR
(FR) SYSTÈMES ET PROCÉDÉS D'AMORTISSEMENT ACTIF D'UN MOTEUR
Abstract:
(EN) A method includes controlling a first power output to an electric machine during a transient event. Controlling the first power output includes measuring values of the first power output provided to the electric machine during the transient event, receiving an estimated speed input of the electric machine, determining adjustment commands to compensate the first power output for the transient event of the electric machine, generating switch commands for gate drives of a variable frequency drive (VFD) based at least in part on the adjustment commands, and modifying the first power output during the transient event based on the switch commands.
(FR) L'invention concerne un procédé comprenant la commande d'une première sortie de puissance à une machine électrique pendant un événement transitoire. La commande de la première sortie de puissance comprend la mesure de valeurs de la première sortie de puissance fournie à la machine électrique pendant l'événement transitoire, la réception d'une entrée de vitesse estimée de la machine électrique, la détermination d'ordres de réglage pour compenser la première sortie de puissance pour l'événement transitoire de la machine électrique, la génération d'ordres de commutation pour des commandes de grille d'un entraînement à fréquence variable (EFV) sur la base, au moins en partie, des ordres de réglage et la modification de la première sortie de puissance pendant l'événement transitoire sur la base des ordres de commutation.
