Nicola ZAUPA

I’m a Postdoctoral Researcher in the MODUS team at GIPSA-lab (Grenoble, France), working with Bogdan Robu and Matteo Tacchi on the ANR project RADYAL, focusing on energy-aware control for neural network optimization. Previously, I was a Postdoctoral Researcher in the MAC team at LAAS–CNRS, working with Sophie Tarbouriech and Samuele Zoboli on LMI-based control integration in neural networks. I completed my Ph.D. at LAAS–CNRS under the supervision of Isabelle Queinnec and Luca Zaccarian, studying control of resonant converters, with experimental work in collaboration with Carlos Olalla and Luis Martínez-Salamero at URV (Spain). My research interests include mechatronics, power electronics, control, and robotics, with a strong focus on practical implementation and hardware validation.

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.
