Abstract
(EN)
Systems and methods for controlling a resonant device are described. One described method for braking an actuator includes generating a first actuator signal configured to drive the actuator, the first actuator signal having a first frequency approximately resonant to the actuator, and transmitting the first actuator signal to the actuator. The method also includes generating a second actuator signal, having a second frequency approximately 180 degrees out of phase to the first frequency, the second actuator signal configured to cause a braking force on the actuator, and transmitting the second actuator signal to the actuator.

L'invention concerne des systèmes et des procédés de commande d'un dispositif résonant. Un procédé de freinage d'un actionneur de l'invention consiste à générer un premier signal d'actionnement conçu pour commander l'actionneur, le premier signal d'actionnement présentant une première fréquence approximativement résonante pour l'actionneur, ainsi qu'à transmettre le premier signal d'actionnement à l'actionneur. Le procédé consiste également à générer un second signal d'actionnement, présentant une seconde fréquence approximativement déphasée de 180 degrés par rapport à la première fréquence, le second signal d'actionnement étant conçu pour entraîner une force de freinage sur l'actionneur, ainsi qu'à transmettre le second signal d'actionnement à l'actionneur.
