Abstract :

Cooperative control of multi-agent systems (multiple autonomous vehicles) has received compelling attention from various scientific communities due to its broad applications in such areas as satellite formation flying, sensor networks, surveillance and reconnaissance, air traffic control, and future autonomous combat systems. Distributed systems of agents linked by communication networks only have access to local information from their neighboring agents, yet must cooperatively achieve global agreement on team activities. In the area of cooperative control of multi-agent systems, consensus is an important and fundamental problem, which has applications in rendezvous, formation control, flocking, and attitude alignment.

The purpose of this talk is to present our recent results on the consensus and tracking problem of multi-agent systems with general linear agent dynamics. Problems such as "how to reach consensus", "how to track a leader with (unknown) bounded input", and "how to design consensus protocols" will be addressed. A unified approach built on the consensus region notion will be given. The traditional observer-based controller for a single agent will be extended to the multi-agent system setting. Distributed adaptive controllers will be introduced to achieve consensus and tracking in a fully distributed fashion. Distributed discontinuous controllers based on the sliding mode control idea will be designed to ensure that a group of followers can follow a leader with unknown bounded input.
