Paper Abstract

Control of vibration of a base excited cantilever beam is studied in this paper. The algorithm of the control system is based on the concept of active attenuation; the traveling wave of the structural response caused by external excitation can be annihilated by a control wave of opposite signature. Collocated sensor and actuator are used to sensing the traveling wave and generating the control wave. Experimental and numerical results showed that the vibration of a cantilevered beam is substantially suppressed.
