Consensus-Based Cooperative Control
Consensus algorithms, which have been used in the field of distributed computing for decades, have recently attracted renewed attention because they can be exploited for distributed cooperative control. Coordination between entities in a group requires that they share information over a network, which is usually modelled as a directed or undirected graph, and develop a consistent view regarding objectives and relevant information on the environment, i.e., reach a consensus. Within this context, we have investigated the following issues.
One concerns a specific class of consensus algorithms, namely max-consensus, which is particularly important in applications such as minimum time rendezvous and leader election. In particular, we have proposed an approach that uses results from the field of max-plus algebra to analyze max-consensus algorithms in both time-invariant and time-variant communication topologies[1] [2].
We have also investigated convergence properties of consensus algorithms, characterized by the Laplacian matrix of the communication graph, for agents with double integrator dynamics. Position and velocity information is exchanged between the agents via different undirected communication networks. It turns out that consensus can be achieved even if neither of the two networks is connected[3] [4].
We have used cooperative communication and distributed optimization techniques to maximize the lifetime of wireless sensor networks in the context of slow-fading communication channels[5].
