Living things have the ability to adapt themselves to various environmental conditions and keep the whole system functioning even if a part of it is out of order. Recently, biological systems of living things which can be modeled as autonomous distributed systems have become the focus of attention. In this paper the modeling of the rhythmic movement generating mechanism of dragonfly wings using nonlinear oscillators is described. A wing is approximately modeled as a 1-DOF or 2-DOF beam and the equations of motion are derived. The central pattern generators(CPG)which generate the rhythmic movement of wings are modeled as a set of Van der Pol nonlinear oscillators. By solving the equations of motion of the wing and the equations of oscillators simultaneously, the rhythmic movement of a dragonfly wing model is obtained. The synchronization of multiple wings is obtained by the interconnection of oscillators. It is found that various autonomous vibrations of dragonfly wings can be reproduced using this model.
