Koopman operator dynamical models
Web28 jan. 2024 · However, the Koopman operator does not account for any uncertainty in dynamical systems, causing it to perform poorly in real-world applications. Therefore, we propose a deep stochastic Koopman operator (DeSKO) model in a robust learning control framework to guarantee stability of nonlinear stochastic systems. Web5 apr. 2024 · operator—in a measure-preserving setting called the Koopman operator [1–5]. Its spectral triple—eigenvalues, eigenfunctions and eigenmodes—can be used in a variety of contexts, from model reduction [5] to stability and control [6]. In practice, we only have access to finite-dimensional data from observations or outputs of numerical ...
