Complexity reduction for resilient state estimation of uniformly observable nonlinear systems

no code implementations18 Apr 2023 Junsoo Kim, Jin Gyu Lee, Henrik Sandberg, Karl H. Johansson

As a result, although a portion of measurements are compromised, they can be locally identified and excluded from the state estimation, and thus the true state can be recovered.

A Design Method of Distributed Algorithms via Discrete-time Blended Dynamics Theorem

no code implementations11 Oct 2022 Jeong Woo Kim, Jin Gyu Lee, Donggil Lee, Hyungbo Shim

We develop a discrete-time version of the blended dynamics theorem for the use of designing distributed computation algorithms.

Open-loop contraction design

no code implementations9 Sep 2022 Jin Gyu Lee, Thiago B. Burghi, Rodolphe Sepulchre

This paper stresses the analogy of this question with the classical question of feedback stabilization.

Rapid and robust synchronization via weak synaptic coupling Extended arXiv version

no code implementations18 Jul 2022 Jin Gyu Lee, Rodolphe Sepulchre

This paper examines how weak synaptic coupling can achieve rapid synchronization in heterogeneous networks.

Node-wise monotone barrier coupling law for formation control

no code implementations6 Feb 2022 Jin Gyu Lee, Cyrus Mostajeran, Graham Van Goffrier

We study a node-wise monotone barrier coupling law, motivated by the synaptic coupling of neural central pattern generators.

Edge-wise funnel output synchronization of heterogeneous agents with relative degree one

no code implementations11 Oct 2021 Jin Gyu Lee, Thomas Berger, Stephan Trenn, Hyungbo Shim

However, to compute the magnitude of the coupling gain, each agent needs to know global information such as the number of participating nodes, the graph structure, and so on, which prevents a fully decentralized design of the node dynamics in conjunction with the coupling laws.

Networks obtained by Implicit-Explicit Method: Discrete-time distributed median solver

no code implementations18 Jun 2021 Jin Gyu Lee

In the purpose of making the consensus algorithm robust to outliers, consensus on the median value has recently attracted some attention.

Design of heterogeneous multi-agent system for distributed computation

no code implementations1 Jan 2021 Jin Gyu Lee, Hyungbo Shim

Under stability of the averaged dynamics (not asking stability of individual agents), the behavior of heterogeneous multi-agent system can be estimated by the solution to the averaged dynamics.

Synchronization with prescribed transient behavior: Heterogeneous multi-agent systems under funnel coupling Extended arXiv version

no code implementations29 Dec 2020 Jin Gyu Lee, Stephan Trenn, Hyungbo Shim

The proposed coupling law is motivated by the so-called funnel control method studied in adaptive control under the observation that arbitrary precision synchronization can be achieved for heterogeneous multi-agent systems by a high-gain coupling; consequently we call our novel synchronization method `(node-wise) funnel coupling.'

Fully Distributed Resilient State Estimation based on Distributed Median Solver

no code implementations16 Feb 2020 Jin Gyu Lee, Junsoo Kim, Hyungbo Shim

In this paper, we present a scheme of fully distributed resilient state estimation for linear dynamical systems under sensor attacks.
