In this paper, the tiltrotor aircraft model is established based on the multi-body dynamics method, in order to further improve the modeling accuracy, an augmented Pitt-Peters dynamic inflow model was used to establish the induced velocity model of the rotor. Based on the presented model, aiming at the uncertainties of the nonlinear dynamics of aircraft, the dynamic surface adaptive backstepping control...
Tiltrotor aircraft is a kind of aircraft which can fly as a fixed wing aircraft or a helicopter by tilting its two rotors' mast angle, which means it has both the advantages of helicopter and fixed wing aircraft. To control it well, a nonlinear mathematical model based on Pitt-Peters dynamic inflow theory is established. Since traditional control method based on linearized model needs extensive gain...
A tilt-rotor has a rotor on each side of its airframe and each rotor can be tilted to provide lift or thrust. With the tilt on rotors, the model of tilt-rotor has a significant change. Conventional control methods based on linearized model need extensive gain scheduling with the nacelle angle and flight condition. In order to alleviate this requirement, a design of attitude control based on ESO(Extended...
