Vehicular Applications of Koopman Operator Theory—A Survey [PDF]

open access: goldIEEE Access, 2023
Koopman operator theory has proven to be a promising approach to nonlinear system identification and global linearization. For nearly a century, there had been no efficient means of calculating the Koopman operator for applied engineering purposes.

On Koopman Operator for Burgers' Equation [PDF]

open access: greenPhysical Review Fluids, 2021
We consider the flow of Burgers' equation on an open set of (small) functions in $L^2([0,1])$. We derive explicitly the Koopman decomposition of the Burgers' flow. We identify the frequencies and the coefficients of this decomposition as eigenvalues and eigenfunctionals of the Koopman operator. We prove the convergence of the Koopman decomposition for $

Dynamical systems and complex networks: a Koopman operator perspective [PDF]

open access: yesJournal of Physics: Complexity
The Koopman operator has entered and transformed many research areas over the last years. Although the underlying concept—representing highly nonlinear dynamical systems by infinite-dimensional linear operators—has been known for a long time, the ...

Decompositions of dynamical systems induced by the Koopman operator [PDF]

open access: greenAnalysis Mathematica, 2019
For a topological dynamical system we characterize the decomposition of the state space induced by the fixed space of the corresponding Koopman operator. For this purpose, we introduce a hierarchy of generalized orbits and obtain the finest decomposition of the state space into absolutely Lyapunov stable sets. Analogously to the measure-preserving case,

Nonparametric Control-Koopman Operator Learning: Flexible and Scalable Models for Prediction and Control [PDF]

open access: yesarXiv.org
This paper presents a novel Koopman composition operator representation framework for control systems in reproducing kernel Hilbert spaces (RKHSs) that is free of explicit dictionary or input parametrizations. By establishing fundamental equivalences between different model representations, we are able to close the gap of control system operator ...

Koopman Operator Applications in Signalized Traffic Systems [PDF]

open access: greenIEEE Transactions on Intelligent Transportation Systems, 2019
This paper proposes Koopman operator theory and the related algorithm dynamical mode decomposition (DMD) for analysis and control of signalized traffic flow networks. DMD provides a model-free approach for representing complex oscillatory dynamics from measured data, and we study its application to several problems in signalized traffic. We first study

On Numerical Approximations of the Koopman Operator

open access: yesMathematics, 2022
We study numerical approaches to computation of spectral properties of composition operators. We provide a characterization of Koopman Modes in Banach spaces using Generalized Laplace Analysis.
