Gyroplane is becoming popular these days for its characters of security, reliable and simple operation. Modeling is the first step that put mathematical theory into engineering studies such as aircraft stability, control and handling qualities. Considering the variable rotoring speed, propeller, tail aero forces and moment, this paper explores the mathematical model of an unmanned mode gyroplane based...
The ability to transition between vertical and horizontal flight is of great importance to convertible unmanned aerial vehicles. A novel convertible UAV-a Quad Tilt Rotor UAV (QTR UAV) was designed, which could operate as a quad rotor as well as an airplane by means of transition maneuver. This paper focuses on the trajectory tracking control for the hovering mode and acceleration maneuver which is...
An oblique cross quad rotor UAV is designed and assembled. To achieve autonomous flight control, a nonlinear dynamic model is investigated. Then an adaptive flight control theory, based on dynamic inversion and linear neural network, is introduced to the control of the UAV. Based on the time-scale separation principle, an attitude dynamic inverse controller and a trajectory dynamic inverse controller...
