Risk of Collision and Detachment in Vehicle Platooning: Time-Delay-Induced Limitations and Trade-Offs (Extended Version)
Christoforos Somarakis, Yaser Ghaedsharaf, Nader Motee
We quantify the value-at-risk of inter-vehicle collision and detachment for a class of platoons, which are governed by second-order dynamics in presence of communication time-delay…
Performance Improvement in Noisy Linear Consensus Networks with Time-Delay
Yaser Ghaedsharaf, Milad Siami, Christoforos Somarakis +1
We analyze performance of a class of time-delay first-order consensus networks from a graph topological perspective and present methods to improve it. The performance is measured b…
Aggregate Fluctuations in Networks with Drift-Diffusion Models Driven by Stable Non-Gaussian Disturbances
Christoforos Somarakis, Nader Motee
The focus of this paper is to quantify measures of aggregate fluctuations for a class of consensus-seeking multiagent networks subject to exogenous noise with alpha-stable distribu…
Koopman Performance Analysis of Nonlinear Consensus Networks
Hossein K. Mousavi, Christoforos Somarakis, Qiyu Sun +1
Spectral decomposition of dynamical systems is a popular methodology to investigate the fundamental qualitative and quantitative properties of these systems and their solutions. In…
Time-Delay Origins of Fundamental Tradeoffs Between Risk of Large Fluctuations and Network Connectivity
Christoforos Somarakis, Yaser Ghaedsharaf, Nader Motee
For the class of noisy time-delay linear consensus networks, we obtain explicit formulas for risk of large fluctuations of a scalar observable as a function of Laplacian spectrum a…
