Promoting global stability in data-driven models of quadratic nonlinear dynamics [PDF]

open access: yesPhysical Review Fluids, 2021
Modeling realistic fluid and plasma flows is computationally intensive, motivating the use of reduced-order models for a variety of scientific and engineering tasks. However, it is challenging to characterize, much less guarantee, the global stability (i.

Multi-agent Performative Prediction: From Global Stability and Optimality to Chaos [PDF]

open access: yesACM Conference on Economics and Computation, 2022
The recent framework of performative prediction [Perdomo et al. 2020] is aimed at capturing settings where predictions influence the outcome they want to predict. In this paper, we introduce a natural multi-agent version of this framework, where multiple

Global Stability Analysis for Synchronous Reference Frame Phase-Locked Loops

open access: yesIEEE transactions on industrial electronics (1982. Print), 2021
This article analyzes the global stability of synchronous reference frame phase-locked loops (SRF-PLLs) from a large signal viewpoint. First, a large-signal model of SRF-PLL is accurately established, without applying any linearization method.

Global stability of fuzzy cognitive maps

open access: yesNeural computing & applications (Print), 2021
Complex systems can be effectively modelled by fuzzy cognitive maps. Fuzzy cognitive maps (FCMs) are network-based models, where the connections in the network represent causal relations.

The birth of the global stability theory and the theory of hidden oscillations [PDF]

open access: yesEuropean Control Conference, 2020
The first mathematical problems of the global analysis of dynamical models can be traced back to the engineering problem of the Watt governor design. Engineering requirements and corresponding mathematical problems led to the fundamental discoveries in ...

Global Stability of Minkowski Space for the Einstein-Vlasov System in the Harmonic Gauge. [PDF]

open access: yesArch Ration Mech Anal, 2020
Minkowski space is shown to be globally stable as a solution to the massive Einstein–Vlasov system. The proof is based on a harmonic gauge in which the equations reduce to a system of quasilinear wave equations for the metric, satisfying the weak null ...

Global Stability Analysis of Fractional-Order Quaternion-Valued Bidirectional Associative Memory Neural Networks

open access: yesMathematics, 2020
We study the global asymptotic stability problem with respect to the fractional-order quaternion-valued bidirectional associative memory neural network (FQVBAMNN) models in this paper.

An Approach for the Global Stability of Mathematical Model of an Infectious Disease

open access: yesSymmetry, 2020
The global stability analysis for the mathematical model of an infectious disease is discussed here. The endemic equilibrium is shown to be globally stable by using a modification of the Volterra–Lyapunov matrix method.

Truss geometry and topology optimization with global stability constraints

open access: yesStructural And Multidisciplinary Optimization, 2020
In this paper, we introduce geometry optimization into an existing topology optimization workflow for truss structures with global stability constraints, assuming a linear buckling analysis.

Global Stability of Fluid Flows Despite Transient Growth of Energy. [PDF]

open access: yesPhysical Review Letters, 2019
Verifying nonlinear stability of a laminar fluid flow against all perturbations is a central challenge in fluid dynamics. Past results rely on monotonic decrease of a perturbation energy or a similar quadratic generalized energy.
