| 1 | Coordinated flight control of miniature fixed-wing UAV swarms: methods and experiments显示文摘In this paper,we present our recent advances in both theoretical methods and field experiments for the coordinated control of miniature fixed-wing unmanned aerial vehicle(UAV)swarms.We propose a multi-layered group-based architecture,which is modularized,mission-oriented,and can implement large-scale swarms.To accomplish the desired coordinated formation flight,we present a novel distributed coordinated-control scheme comprising a consensus-based circling rendezvous,a coordinated path-following control for the leader UAVs,and a leader-follower coordinated control for the follower UAVs.The current framework embeds a formation pattern reconfiguration technique.Moreover,we discuss two security solutions(inter-UAV collision avoidance and obstacle avoidance)in the swarm flight problem.The effectiveness of the proposed coordinated control methods was demonstrated in field experiments by deploying up to 21 fixed-wing UAVs. | Xiangke WANG Lincheng SHEN Zhihong LIU Shulong ZHAO Yirui CONG Zhongkui LI Shengde JIA Hao CHEN Yangguan YU Yuan CHANG Yajing WANG | 2019 | Science China(Information Sciences)2019，62，11： | 21 |
| 2 | Formation flight of fixed-wing UAV swarms:A group-based hierarchical approach显示文摘This paper investigates a formation control problem of fixed-wing Unmanned Aerial Vehicle(UAV) swarms. A group-based hierarchical architecture is established among the UAVs, which decomposes all the UAVs into several distinct and non-overlapping groups. In each group, the UAVs form hierarchies with one UAV selected as the group leader. All group leaders execute coordinated path following to cooperatively handle the mission process among different groups, and the remaining followers track their direct leaders to achieve the inner-group coordination. More specifically, for a group leader, a virtual target moving along its desired path is assigned for the UAV, and an updating law is proposed to coordinate all the group leaders’ virtual targets;for a follower UAV, the distributed leader-following formation control law is proposed to make the follower’s heading angle coincide with its direct leader, while keeping the desired relative position with respect to its direct leader. The proposed control law guarantees the globally asymptotic stability of the whole closed-loop swarm system under the control input constraints of fixed-wing UAVs. Theoretical proofs and numerical simulations are provided, which corroborate the effectiveness of the proposed method. | Hao CHEN Xiangke WANG Lincheng SHEN Yirui CONG | 2021 | Chinese Journal of Aeronautics2021，34，2： | 12 |
