This paper describes an active vibration control system combining a piezoelectric electrode configured with a novel switching control system to achieve multimodal vibration suppression in smart flexible structures embedded with only a single piezoelectric actuator. The fact that high-frequency vibrations attenuate more rapidly than do low frequency vibrations motivated the development of a novel scheme...
A single piezoelectric resonator shows better excitation efficiency at bending modes than other vibration modes and the inherent operating principle of piezoelectric actuators has limited its practical use to suppressing bending mode vibrations. To achieve effective non-bending modal vibration attenuation using only one piezoelectric actuator, this paper presents an active vibration control method...
