Resumo
This work proposes a nonlinear W∞ controller for a convertible tilt-rotor Unmanned Aerial Vehicle (UAV) in order to solve the trajectory tracking problem during the helicopter-flight mode. The control design for such aircraft is challenging since it is a multi-body, highly-coupled, underactuated mechanical system. Therefore, a controller based on the novel nonlinear W∞ control approach is designed aiming to guide the translational position and yaw angle toward a desired trajectory, while the remaining degrees of freedom are stabilized. Numerical experiments are carried out to corroborate the efficiency of the control strategy demonstrating robustness, good transient performance and fast response against external disturbances.
