   Equivalent Conditions for the Synchronization of Identical Linear Systems over Arbitrary Interconnections

   Nicola Zaupa, Giulia Giordano, Isabelle Queinnec, Sophie Tarbouriech, and Luca Zaccarian

   Aug 2024

   Abs DOI arXiv HAL Bib

   We propose necessary and sufficient conditions for the synchronization of \N identical single-input-single-output (SISO) systems, connected through a directed graph. We consider both the continuous-time and the discrete-time case, and we provide conditions that do not require any assumption on the graph and ensure the uniform global exponential stability of the closed attractor that corresponds to the synchronization set, with guaranteed convergence rate.

   Controlling Identical Linear Multi-Agent Systems Over Directed Graphs

   Nicola Zaupa, Luca Zaccarian, Sophie Tarbouriech, Isabelle Queinnec, and Giulia Giordano

   In 2023 62nd IEEE Conference on Decision and Control (CDC), Dec 2023

   ISSN: 2576-2370

   Abs DOI arXiv HAL Bib

   We consider the problem of synchronizing a multiagent system (MAS) composed of several identical linear systems connected through a directed graph. To design a suitable controller, we construct conditions based on Bilinear Matrix Inequalities (BMIs) that ensure state synchronization. Since these conditions are non-convex, we propose an iterative algorithm based on a suitable relaxation that allows us to formulate Linear Matrix Inequality (LMI) conditions. As a result, the algorithm yields a common static state-feedback matrix for the controller that satisfies general linear performance constraints. Our results are achieved under the mild assumption that the graph is time-invariant and connected.
