Abstract
The problem of controlling the bending vibration of cantilevers modeled as thin-walled beams of closed cross-section incorporating a number of nonclassical effects, such as transverse shear, secondary warping and heterogeneity, is investigated. The control is carried out by means of piezoelectric materials bonded or embedded into the host structure. The control law represents a combination of displacement, velocity and acceleration feedback. The capabilities and efficiency of this control methodology are illustrated and a number of relevant conclusions are outlined.
