Study on Cable-Stayed Bridge Flutter Active Control by a Single Group of ADM

At present, scholars at home and abroad have studied more on the passive control of cable-stayed bridge flutter, while less studied on the active control, and only considered the controlled equation of cable-stayed bridge controlled by a single active mass damper and the motion equation of a single AMD, so research on a single group ADM to active control of cable-stayed bridge flutter is of theoretical and practical engineering significance. According to modern control theory, a theoretical analysis is conducted on the active control of cable-stayed bridge flutter, it is established that the controlled equation of cable-stayed bridge controlled by a single active mass damper and the motion equation of a single AMD to determine the calculation method of the critical flutter velocity under the controlled status of the cable-stayed bridge. An example shows that a single group ADM is a good means to prevent the flutter damage of long-span cable-stayed bridges.
