Distributed Information Processing and Control of Multi-agent Networks

Lihua Xie
Nanyang Technological University, Singapore


Multi-agent cooperation involves a collection of decision-making components with limited processing, limited sensing and limited communications capabilities, all seeking to achieve a collective objective. Well known examples include mobile sensor networks for environment monitoring and surveillance and multi-UAV (unmanned aerial vehicle) formation flight. The distributed nature of information processing, sensing and actuation makes these applications a significant departure from the traditional centralized control system paradigm. There have been many approaches to multi-agent cooperation. In this talk, we shall focus on a consensus based approach and discuss issues related to limited communications (communication topology and data rate) and their impacts on the performance of multi-agent systems. A fundamental relationship between distributed consensusability and agent dynamics, network topology and communication data rate will be revealed. The application of the distributed consensus in formation control will be demonstrated.
