In this paper, a novel data-driven control (DDC) algorithm is proposed to adaptive control for fixed-wing (Unmanned Aerial Vehicle) UAV path following using input and output (I/O) data. Differently from model based control, data-driven control reduces the dependence of accurate mathematics model in process of controller designation. The key difficulty in fixed-wing UAV path following is that the model...
This paper describes our work on formation flight control of unmanned aerial vehicles (UAVs). A formation flight test system from theory to actual flight is developed to narrow the gap between the theory and the practice. Firstly, a leader-follower based 3D formation control algorithm is designed and validated via numerical simulation. Secondly, the method is embedded realized in our autopilot, then...
This paper presents a new ground-based visual approach for guidance and safe landing of an unmanned aerial vehicle (UAV) in Global Navigation Satellite System(GNSS)-denied environments. In our previous work, the old system consists of one pan-tilt unit(PTU) with two cameras, whose detection range is limited by the baseline. To achieve long-range detection and cover wide field of regard, we mounted...
To the problem of standoff Ground Moving Target Tracking using a fixed-wing UAV, a novel solving framework is presented, which based on target state estimation, prediction and on-line motion planning. First of all, a solving framework was presented, the formal representation and system model of standoff tracking using Fixed-wing UAV was established; next, the Unscented Kalman Filter was suggested...
To the problem of cooperative ground moving target tracking using UAVs in an urban area, a novel method is presented, which based on target state fusion estimation and prediction, as well as on-line trajectory planning. Firstly, based on active sensing, a solving framework was presented, the formal representation and system model of cooperative target tracking using a team UAVs was established; secondly,...
This paper proposes a new method with a three-level architecture named tactics template (TT) for tactical aircraft attack path planning and optimization. Distinguished from the traditional path planning algorithms, the TT method extends the ability to deal with tactics and actions rather than trajectories, which maintains the benefits of traditional path planning algorithms while well-satisfying pilot's...
