Convergent Dynamic Mode Decomposition

2023 62nd IEEE Conference on Decision and Control (CDC), 2023
This manuscript addresses convergence of dynamic mode decomposition (DMD) algorithms and the existence of associated Koopman modes. Convergence relies on reformulation of dynamic mode decomposition in terms of newly defined compact operators defined with

Dynamic Mode Decomposition and Its Variants

Annual Review of Fluid Mechanics, 2021
Dynamic mode decomposition (DMD) is a factorization and dimensionality reduction technique for data sequences. In its most common form, it processes high-dimensional sequential measurements, extracts coherent structures, isolates dynamic behavior, and ...

The Multiverse of Dynamic Mode Decomposition Algorithms

arXiv.org, 2023
Dynamic Mode Decomposition (DMD) is a popular data-driven analysis technique used to decompose complex, nonlinear systems into a set of modes, revealing underlying patterns and dynamics through spectral analysis.

Data-Driven MPC With Stability Guarantees Using Extended Dynamic Mode Decomposition

IEEE Transactions on Automatic Control, 2023
For nonlinear (control) systems, extended dynamic mode decomposition (EDMD) is a popular method to obtain data-driven surrogate models. Its theoretical foundation is the Koopman framework, in which one propagates observable functions of the state to ...

An improved mode time coefficient for dynamic mode decomposition

The Physics of Fluids, 2023
Dynamic mode decomposition (DMD) is widely used for extracting dominant structures of unsteady flow fields. However, the traditional mode time coefficient of DMD is assumed to change exponentially over the time.
