Aeroelastic vibration control of hybrid airships using Regenerative Actuators

Abstract

In this paper, an experiment is performed to investigate aeroelastic vibration control of a wing using regenerative piezoelectric actuators. Instead of the wing a plate with one pair of the piezoelectric actuator is used to study the effect of the vibrations. The model consists of the rectangular steel modelled in the cantilever configuration with the surface bonded with piezoelectric actuators. The regenerative actuators is used in the cantilever beam to harvest electrical power from the vibratory motion or provide an anti-vibratory control motion to cancel out the undesirable vibration in the cantilever beam.
