Abstract
A 2-DOF piezo-actuated flapping mechanism was designed according to the theory of flapping-wing flying rhythmic movement of insects. Based on the physical model of flapping-wing, the modal shapes were studied. A van der Pol type self-excited vibratory system was constructed by active control, and the flapping-wing could generate stable limit-circle movement. Through the research on system responses, the influences of the parameters in the control force on the system characteristics were analyzed. Then the first modal vibration of the system was selected by cross feedback, and the flapping-wing micro air vehicle realized different flying modes by adjusting system parameters.
