| Abstract: | One of the aero elastic phenomena associated with composite structure in high performance aircraft is the high frequency vortex induced out of plane buffeting load. The buffeting load can lead to high cyclic strain and stress, and dramatically reduce the fatigue life of composite structures. In this paper, piezoelectric patches are bonded on the surface of composite panel. The response of the structure is measured using bonded piezoelectric sensors. A filtered adaptive controller is used to control the deformation of piezoelectric actuators actively, so as to increase the modal damping coefficient of the panel, suppress the dynamic response and to improve the fatigue performance of the structure. Experimental results indicate that the strain in composite structures can be suppressed effectively. |
