Abstract: Cameras have been applied as one of major sensors on Unmanned Aerial Vehicles (UAVs) for different purposes, such as data capturing and communication. This talk considers the problem of UAV formation through fish-eye cameras with limited Field of View (FOV) when other sensing and communication resources are degraded or faulted. The concept of Compatible Formation is introduced on the visual communication graph to characterize the group flying pattern of UAVs such that no blind spots are exhibited. It is shown that, if a formation is deemed as compatible under this new concept, a distributed control algorithm could then be developed and applied to steer UAVs into a visible region of some others, hence keeping the UAV group of the interest visually connected.

摘要：

多自主体系统协同控制属于自动控制理论与应用领域的核心关键问题,是当前国际系统与控制领域的前沿研究方向，在无人集群系统、传感器网络、军事航天等领域均有重大应用前景，具有重要研究意义。协同控制的核心课题是设计基于局部信息的分布式协同控制律，以实现期望的集群行为。分布式控制律与自主体动力学、网络拓扑等存在复杂耦合关系，这使得分布式控制律设计具有挑战性。本报告将介绍我们在分布式协同控制方面的近期研究进展，首先阐述我们提出的一致性区域框架，进而给出了完全分布式协同控制律设计、基于事件触发的协同控制等理论成果，最后汇报我们在无人机集群方面的一些进展。
