In this paper, a robust trajectory tracking control strategy using disturbance observer is developed for a quadrotor Unmanned Aerial Vehicle (UAV) in the presence of external aerodynamic disturbance. Considering the external aerodynamic disturbance force, a backstepping control scheme is designed for the position subsystem to ensure that the quadrotor UAV can track the reference position signal rapidly...
The paper presents a new robust adaptive augmented backstepping control scheme for rapid turning maneuver of a high agility unmanned aerial vehicle (UAV). The proposed control scheme consists of a baseline backstepping controller which can deal with the couplings of kinematic and inertial during fast rolling and generates commands tracking control inputs, and a robust adaptive compensator which can...
