How does forcing affect the DMD modes and eigenvalues?

Residual-Dynamic-Mode-Decomposition. Computation of spectral properties of Koopman operators associated with discrete-time autonomous dynamical systems. Jun 5, 2015 ... We will show that this approach is, in effect, an extension of dynamic mode decomposition (DMD), which has been used to approximate the Koopman ... Dec 29, 2023 ... We develop a novel core surface flow inversion scheme based on physics-informed neural networks. The inversion method can account for the secular variation. Nov 13, 2019 ...

DMD is a modal decomposition algorithm that describes high-dimensional dynamic data using coupled spatial–temporal modes. We propose a modal decomposition algorithm to perform the analysis using finite-length data sequences generated from a nonlinear system. ... dynamic mode decomposition to reconstruct the final steady state given only few snapshots of the simulation, and the reduction of the parameter space by AS ...
