This paper presents the design of a vibration control mechanism for a beam withbonded piezoelectric sensors and actuators and an application of the arising smartstructure for suppression of wind-induced vibrations. The mechanical modeling ofthe structure and the subsequent finite element approximation are based on theclassical equations of motion, as they are derived from Hamilton’s principle, inconnection with simplified modeling of the piezoelectric sensors and actuators.Various control schemes have been implemented in structural control (LQR, LQG,H2, and H ∞ ). The latter robust controllers are more flexible and lead to applicabledesign of smart structures. The numerical simulation shows that sufficient vibrationsuppression can be achieved by means of this general method
