Exponential Convergence of the Discrete-Time Altafini Model
Ji Liu, Xudong Chen, Tamer Basar +1
This paper considers the discrete-time version of Altafini's model for opinion dynamics in which the interaction among a group of agents is described by a time-varying signed digra…
Undirected Rigid Formations are Problematic
Shaoshuai Mou, A. Stephen Morse, Mohamed Ali Belabbas +2
By an undirected rigid formation of mobile autonomous agents is meant a formation based on graph rigidity in which each pair of "neighboring" agents is responsible for maintaining…
Distributed Evaluation and Convergence of Self-Appraisals in Social Networks
Xudong Chen, Ji Liu, M. -A. Belabbas +2
We consider in this paper a networked system of opinion dynamics in continuous time, where the agents are able to evaluate their self-appraisals in a distributed way. In the model…
Geometric methods for optimal sensor design
M. -A. Belabbas
An observer is an estimator of the state of a dynamical system from noisy sensor measurements. The need for observers is ubiquitous, with applications in fields ranging from engine…
Consensus with Linear Objective Maps
Xudong Chen, M. -A. Belabbas, Tamer Basar
A consensus system is a linear multi-agent system in which agents communicate to reach a so-called consensus state, defined as the average of the initial states of the agents. Cons…
