Active suppression of panel flutter with piezoelectric actuators using eigenvector orientation method

▶ We use eigenvector orientation method to detect the onset of flutter. ▶ Piezoelectric layers are assumed to be bonded to the surface of panel to suppress flutter. ▶ Three cases are studied to illustrate the effectiveness of piezoelectric actuators. ▶ Controllers can move the flutter boundary to a higher speed. ▶ Using control moments on more elements seems to be more effective to shift flutter.
