Abstract
Dear Editor, In this letter, a vision-based fixed-time control is proposed for an unmanned aerial vehicle (UAV) with actuator saturation to track an uncooperative target. The fixed-time control is designed in backstepping framework. The relative states between UAV and the target are not directly measured, and are estimated by an onboard monocular camera. It is proved that, the closed loop UAV with actuator saturation is capable of reaching the target before a fixed time. The fixed time can be estimated, and it is independent of initial states.
