ACTIVE VIBRATION CONTROL FOR FLEXIBLE STRUCTURES USING A WAVE-ABSORBING CONTROL METHOD

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