Abstract
A concept for active vibration suppression with a so called bandpass absorber (BPA) is presented. A properly designed compensator in the active feedback converts the well-known passive absorber into a bandpass absorber. Such an absorber amplifies frequencies in a given frequency range, thus producing almost the resonance for all these frequencies. If such an absorber is attached to a vibrating body, it absorbs vibrations at all frequencies that belong to the bandpass range. The presented compensator design guarantees the stability of the system. The proposed concept needs an additional local control of the absorber mass displacement. The paper presents the idea, the design procedure, and the simulation results that prove the relevance of the solution.
