Design of smart beams for suppression of wind-induced vibrations

Summarization: This paper presents the design of a vibration control mechanism for a beam with bonded piezoelectric sensors and actuators and an application of the arising smart structure for suppression of wind-induced vibrations. The mechanical modeling of the structure and the subsequent finite element approximation are based on the classical equations of motion, as they are derived from Hamilton’s principle, in connection 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 applicable design of smart structures. The numerical simulation shows that sufficient vibration suppression can be achieved by means of this general methodΠαρουσιάστηκε στο: Proceedings of the Ninth International Conference on Civil and Structural Engineering Computin
