As a practical example of a self-excited actuator theoretically presented in the previous paper, we developed an extended theory of the two-degree-of-freedom swing wing vibratory mechanism and showed its experimental prototype as a model of insect wings. In order to realize a self-excited system, we proposed not only a positive velocity feedback with nonlinear damping similar to the Van der Pole system, but also a more efficient Coulomb friction-type positive feedback system. Since the first-mode swing motion tends to be drawn into the second-mode limit cycle, we proposed two methods to excite only the first mode : one of them is the suppression of the second mode by means of a low-pass filter and the other is a cross feedback capable of exciting either mode.
