Abstract
This research work focuses on the analysis of several information-exchange topologies to deploy cooperative tracking for multi-agent systems with spacecrafts as agents. Cooperative tracking control or leader following consensus control consists of a virtual leader and the states of the followers are driven to those of the leader. In the cooperative tracking control, the leader and followers exchange the information through proper communication graph topology. The information exchange among the agents can happen at different levels from the leader to followers. To achieve perfect trajectory tracking of the leader and the followers, the agents are required to be connected in a proper communication topology. This paper mainly aims to identify the efficient topology for the multi-agent systems with spacecrafts as agents. The simulation results highlight the comparison of one leader and two follower topology with one leader and three followers topology that accommodates a virtual leader spacecraft and arbitrary information flow among the spacecrafts by considering different levels of information exchange. In general, for an efficient topology, the leader’s state should be available to all the spacecrafts and there should be proper information exchange between the follower spacecrafts.
