Abstract

In this work, we investigated active flutter control of a bridge section model equipped with arrays of flaps. Three control algorithms, based on an amplitude-gain and a phase-shift, for actuating the flaps and stabilizing the section model have been investigated. A linear analytical model of the structural and aeroelastic forces during flutter has been leveraged in order to find efficient control parameters. The work has been validated with wind tunnel experiments, where all the algorithms were shown capable of suppressing flutter, and the most efficient one was using all of the flaps on the deck.
