Abstract: The dynamic vibration absorber is a well-known vibration control device. Its performance can be enhanced by a proper synthesis of the coupling force between the absorber mass and the primary structure. This study proposes a locally controlled absorber that uses only a feedback signal measured at the coupling point. The absorber is based on an identified transfer function and tolerates identification errors. It is able to introduce global damping into the closed-loop primary structure, and it absorbs vibration at tuned frequencies. Simulation results are presented to verify the theoretical results.
