Abstract :
This paper presents dynamic analysis and control of a single tilt-wing unmanned aerial vehicle. A single tilt-wing shown in this paper has the advantage of flying like a fixed-wing aircraft with vertical take-off and landing capability. A variety of flight modes including fixed-wing, VTOL, and transition mode are considered. Dynamic model is obtained using rotor thrust, aerodynamic lift and drag due to the induced velocity from the rotor, and unwetted aerodynamic forces and moments. Trim analysis is conducted based on gradient method from the nonlinear dynamics. A model-based control system is designed and flight tested successfully.
