This study proposed a partitioned method with a feedback control to analyzed maneuvering of insects during flapping flight. This method decomposed the insect flapping flight into wing and body subsystems and then coupled them using feedback control. In the wing subsystem, the strong coupling of the flexible wings and surrounding fluid was accurately analyzed using the finite element method to obtain the thrust forces acting on the insect’s body. The resulting thrust forces were passed from the wing subsystem to the body subsystem, and then rigid body motion was analyzed in the body subsystem. The controlling of wing subsystem is done by the feedback control using the body angular displacement and velocity. The fundamental performance of the proposed method is demonstrated from the comparison between the present results and the actual observation of maneuver.
