Abstract

Active vibration control of flexible structures has gained much attention in the last decades. The major components of any active vibration control system are the mechanical structure suseptible to vibration, sensor(s) to perceive it, actuator(s) to counteract the influence of disturbances causing vibration and finally, the controller responsible for the generation of appropriate control signals. In this paper, a Lyapunov function controller and a strain rate feedback controller (SRF) are used to attentuate the vibrations of a cantilivered smart beam excited by its first eigenmode. A super element (SE) with a finite number of degrees of freedom (DOF) is derived from the modified and damped finite element (FE) model. The state-space (SS) equations of the same model are also extracted. Controllers are applied to the SE and SS models and results are presented and compared.
