A new concept for active vibration absorption is presented. A properly designed compensator in the local feedback converts the well-known passive absorber into a bandpass absorber. Such an absorber amplifies frequencies in a given frequency range, thus almost producing resonance for all these freque
Vibrations of machines and structures vanish perfectly at a certain frequency when they have a vibration absorber without damping. But if forced frequencies vary from the anti-resonance frequency, their vibration amplitudes increase signi"cantly. Then the absorber without damping cannot be applied t
A control algorithm emulating a dynamic vibration absorber (DVA) is developed for a flexible structure subject to harmonic disturbances of uncertain frequency. The virtual vibration absorber is mathematically equivalent to a passive DVA, but its stiffness, inertia and damping coefficient are adjusta
