Abstract

A system may detect a vibration being applied to a tuned vibration absorber. The tuned vibration absorber may include a beam, a mass, springs, a sensor, and an actuator. The mass may be disposed on the beam at a current position. The actuator may be configured to adjust a position of the mass on the beam. The system may identify a target position of the mass on the beam based on the detected vibration. The system may generate a drive signal, based on the target position, to control the actuator to adjust the position of the mass on the beam. The system may control the actuator to adjust the position of the mass from the current position on the beam to the target position on the beam to attenuate the vibration.
