Active Vibration Control for Flexible Structures Using a Wave-Absorbing Control Method

Abstract

This paper proposes active vibration control of flexible structures using wave-absorbing method. The method is based on the active restraint of the formation of standing waves which are created in continuous vibration. The Euler-Bernoulli beam is used as the control object. Considering the general solution of the wave equation, we obtain an active control method which eliminates the reflection waves atthe boundary. The effectiveness of the restraint of the resonance is shown in frequency domains. We then apply the method to impulse responses which have wide frequency domains. Consequently, we show that the vibration of the beam is effectively and quickly controlled before the standing waves are formed.
