Abstract :
The traveling wave approach is discussed of the active vibration control of beam. First an active vibration control for the TIMOSHENKO-beam is designed using external control forces. Then vibration control by means of internal forces. i.e. force systems forming equilibrium groups is discussed. Finally an unexpected resonance phenomenon occuring in this approach is explained.
