The dynamics of confusion and consensus in cooperative multi-agent systems

Back
Abstract:
Interest in the dynamics of coordinated and cooperative systems has grown significantly in recent years. Such systems appear in many disciplines; biology (synchronized firefly displays, flocking and schooling behavior), operations management (decentralized dynamic task assignment), environmental science (mobile environmental sensors), aeronautics (autonomous aerial vehicle formations) and computer science (distributed computing consensus) are just a few examples. The focus of this work is high-precision formations and the motivating application is the decentralized control of deep-space interferometric imaging formations. I will examine the issues of confusion and consensus when vehicles estimate each others behavior in the attempt to achieve a common goal and determine the minimum amount of communication required to "control" confusion. The design of distributed estimators over lossy communication channels will be presented.
