How network perturbations distort agreement trajectories in LTI multi-agent systems
Gal Barkai, Irinel-Constantin Morărescu
Distributed coordination of multi-agent systems frequently relies on cooperative protocols designed to achieve agreement on a prescribed, non-trivial trajectory. While the robustne…
Social learning community detection with nonlinear interaction
Anthony Couthures, Athira Varma Jayakumar, Vineeth Satheeskumar Varma +3
Conventional community detection requires centralized network data, making it unsuitable for distributed or privacy-preserving systems. In this paper, we demonstrate that macroscop…
Transient-Safe Platooning via Dynamic Headway
Gal Barkai, J Ér Émie Kreiss, Vineeth S Varma +1
Managing autonomous vehicle platoons requires a delicate balance between string stability and rigorous safety. This challenge is intensified by aggressive transients, such as highw…
From Consensus to Robust Clustering: Multi-Agent Systems with Nonlinear Interactions
Anthony Couthures, Gustave Bainier, Vineeth Satheeskumar Varma +2
This paper establishes a theoretical framework to describe the transition from consensus to stable clustering in multi-agent systems with nonlinear, cooperative interactions. We fi…
Consensus approximation and impulsive control for a class of uncertain multi-agent dynamics
Zoltan Nagy, Irinel-Constantin Morarescu, Lucian Busoniu
This paper studies a class of consensus dynamics where the interactions between agents are affected by a time-varying unknown scaling factor. This situation is encountered in the c…
Bifurcation analysis of an opinion dynamics model coupled with an environmental dynamics
Anthony Couthures, Anastasia Bizyaeva, Vineeth S. Varma +2
We consider an opinion dynamics model coupled with an environmental dynamics. Based on a forward invariance argument, we can simplify the analysis of the asymptotic behavior to the…
Global synchronization of multi-agent systems with nonlinear interactions
Anthony Couthures, Vineeth S. Varma, Samson Lasaulce +1
The paper addresses the synchronization of multi-agent systems with continuous-time dynamics interacting through a very general class of monotonic continuous signal functions that…
Stability of multiplexed NCS based on an epsilon-greedy algorithm for communication selection
Harsh Oza, Irinel-Constantin Morarescu, Vineeth S. Varma +1
In this letter, we study a Networked Control System (NCS) with multiplexed communication and Bernoulli packet drops. Multiplexed communication refers to the constraint that transmi…
A game theory analysis of decentralized epidemic management with opinion dynamics
Olivier Lindamulage De Silva, Samson Lasaulce, Irinel-Constantin Morarescu +1
In this paper, we introduce a static game that allows one to numerically assess the loss of efficiency induced by decentralized control or management of a global epidemic. Each pla…
Discrete-Time Conewise Linear Systems with Finitely Many Switches
Jamal Daafouz, Jérôme Lohéac, Constantin Morărescu +1
We investigate discrete-time conewise linear systems (CLS) for which all the solutions exhibit a finite number of switches. By switches, we mean transitions of a solution from one…
Analysis of a continuous opinion and discrete action dynamics model coupled with an external dynamics
Anthony Couthures, Thomas Mongaillard, Vineeth S. Varma +2
We consider a set of consumers in a city or town (who thus generate pollution) whose opinion is governed by a continuous opinion and discrete action (CODA) dynamics model. This dyn…
A Stackelberg viral marketing design for two competing players
Olivier Lindamulage De Silva, Vineeth Satheeskumar Varma, Ming Cao +2
A Stackelberg duopoly model in which two firms compete to maximize their market share is considered. The firms offer a service/product to customers that are spread over several geo…
Near-optimal control of nonlinear systems with hybrid inputs and dwell-time constraints
Ioana Lal, Constantin Morarescu, Jamal Daafouz +1
We propose two new optimistic planning algorithms for nonlinear hybrid-input systems, in which the input has both a continuous and a discrete component, and the discrete component…
Transmission power policies for energy-efficient wireless control of nonlinear system
Vineeth S. Varma, Romain Postoyan, Daniel E. Quevedo +1
We present a controller and transmission policy design procedure for nonlinear wireless networked control systems. Our objective is to ensure the stability of the closed-loop syste…
On the efficiency of decentralized epidemic management and application to Covid-19
Olivier Lindamulage De Silva, Samson Lasaulce, Irinel-Constantin Morărescu
In this paper, we introduce a game that allows one to assess the potential loss of efficiency induced by a decentralized control or local management of a global epidemic. Each play…
Analysis of the tradeoff between health and economic impacts of the Covid-19 epidemic
Samson Lasaulce, Chao Zhang, Vineeth Varma +1
Various measures have been taken in different countries to mitigate the Covid-19 epidemic. But, throughout the world, many citizens don't understand well how these measures are tak…
Learning control for transmission and navigation with a mobile robot under unknown communication rates
L. Busoniu, V. S. Varma, J. Loheac +4
In tasks such as surveying or monitoring remote regions, an autonomous robot must move while transmitting data over a wireless network with unknown, position-dependent transmission…
Allocating marketing resources over social networks: A long-term analysis
Vineeth S. Varma, Samson Lasaulce, Julien Mounthanyvong +1
In this paper, we consider a network of consumers who are under the combined influence of their neighbors and external influencing entities (the marketers). The consumers' opinion…
Space-time budget allocation policy design for viral marketing
I. C. Morarescu, V. S. Varma, L. Busoniu +1
We address formally the problem of opinion dynamics when the agents of a social network (e.g., consumers) are not only influenced by their neighbors but also by an external influen…
Marketing resource allocation in duopolies over social networks
Vineeth S. Varma, Irinel-Constantin Morarescu, Samson Lasaulce +1
One of the key features of this paper is that the agents' opinion of a social network is assumed to be not only influenced by the other agents but also by two marketers in competit…
