N2 - A study of the vibration control of cantilevers exposed to blast pressure signatures is presented. Whereas the structure used in this analysis is in the form of a thin-walled beam of closed cross-section contour, the control is based upon the simultaneous implementation of the adaptive materials technology and the optimal feedback control. Issues related with the influence upon dynamic response of size and location along the beam span of piezoactuator patches are investigated and the efficiency of this combined control methodology is outlined. Other issues related with the minimization of the input power required in the control process, maximization of the sensing voltage output and implications of the limitation of control input voltage on dynamic response are also addressed and pertinent conclusions are outlined.
