Abstract

Systems of physically interconnected multiple agents cooperating toward a common goal have received considerable attention lately, with applications in large-scale and cyber-physical systems. Distributed consensus ideas have been recognized as a more attractive approach compared to the centralized and decentralized ones. In this talk I will present recent results on stabilization, decoupling, and cooperative tracking in multi-agent systems subject to various types of challenges, such as mixed order linear dynamics, mixed matched/unmatched state-coupled nonlinear uncertainties in the agents’ dynamics. A unifying, easy-to-implement framework is developed using graph theory and optimal control formulation, to provide stability and guaranteed cost of the distributed communication topologies.

This is a joint work with the former PhD student and current postdoctoral DU research associate, Dr. Vahid Rezaei.
