On the NP-Hardness of Unconstrained Static Output Feedback Stabilization
Gal Barkai, Iman Shames
In this paper we give a polynomial-time reduction from the Subset Sum Problem to unconstrained static output feedback stabilization, establishing its NP-hardness. The construction…
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…
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 open-loop representations to closed-loop feedback implementations in differential games: A numerical case study
Philipp Braun, Timothy L. Molloy, Gal Barkai +1
Solutions to pursuit-evasion and surveillance-evasion differential games are typically computed and expressed using open-loop representations, with the synthesis of feedback strate…
On two-degrees-of-freedom agreement protocols
Gal Barkai, Leonid Mirkin, Daniel Zelazo
We propose a distributed two-degrees-of-freedom (2DOF) architecture for driving autonomous, possibly heterogeneous, agents to agreement. The scheme mirrors classical servo structur…
On the Internal Stability of Diffusively Coupled Multi-Agent Systems and the Dangers of Cancel Culture
Gal Barkai, Leonid Mirkin, Daniel Zelazo
We study internal stability in the context of diffusively-coupled control architectures, common in multi-agent systems (i.e. the celebrated consensus protocol), for linear time-inv…
