Novel Dihedral-Based Control of Flapping-Wing Aircraft With Application to Perching [PDF]
IEEE Transactions on Robotics, 2013 We describe the design of an aerial robot inspired by birds and the underlying theoretical developments leading to novel control and closed-loop guidance algorithms for a perching maneuver. A unique feature of this robot is that it uses wing articulation to control the flight path angle as well as the heading angle.

Dynamic Analysis of the Flapping Mechanism of Flapping Wing Aircraft
IOP Conference Series: Materials Science and Engineering, 2019 Abstract In order to improve the design level of bionic flapping-wing aircraft, it is necessary to find out the influence of load undulating moment on the motor under the action of air undulating moment. This paper takes flapping-wing aircraft with a crank and rocker mechanism as a flapping mechanism as an example.
