摘要
We coordinate in discrete time the interaction of two heterogeneous groups of mobile agents: a group of ground vehicles (UGvs) and a group of aerial vehicles (UAVs). The ground agents interact with each other through time-invariant, nearest-neighbour rules. They synchronize their velocities through a specific Communication protocol, and maintain cohesion and separation behaviour by means of interagent potential forces. Ground vehicles estimate their formation's centroid using only locally available delayed information. That same information is transmitted to the aerial group, which orbits above the ground formation's centroid, while avoiding midair collisions. Stability of the ground group motion is established in a Lyapunov framework. A Lyapunov analysis is also used to ensure that UAVS track the ground group's centroid. (c) 2007 Elsevier B.V.
