Rigid body attitude synchronization with communication delays

The paper addresses the cooperative attitude synchronization problem of multiple rigid bodies in the presence of communication delays and without angular velocity measurements. First, we present a solution to the leaderless and leader-follower problems in the case of time-varying communication delays and undirected communication topology. Next, we present an attitude synchronization scheme for the leaderless problem, under a directed graph topology, in the presence of constant communication delays. To demonstrate the effectiveness of the proposed control schemes, simulation results of a scenario of four rigid bodies are provided.
