Active control against wind-induced vibration in structural dynamicsActive control against wind-induced vibration in structural dynamics Πλήρης Δημοσίευση σε Συνέδριο Conference Full Paper 2015-10-132014en This paper presents the design of a vibration control mechanism for a two-dimensional multistory building subjected to wind excitations. The dynamic model of the structure is obtained by finite element approximation. The behavior of the structure is described by simplified linear equations. A linear quadratic regulator and an H2 optimal control method are used for the suppression of the adverse vibration effects. Structured uncertainties are considered to reflect the errors between the model and the reality. To accommodate directly the plant uncertainties and to obtain a best possible performance in the face of uncertainties a robust H∞ optimal control for active control structure is used. The two latter robust controllers take into account as well incompleteness of the measured information, a fact that can not be neglected in civil engineering, and lead to applicable designs of smart structures. The numerical simulation shows that sufficient vibration suppression can be achieved by means of the proposed general methods.http://creativecommons.org/licenses/by/4.0/Proceedings of the International Conference on Urban Wind Engineering and Building Aerodynamics Von Karman Institute Daniela G.
