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

no code implementations12 May 2024 Petar Bevanda, Bas Driessen, Lucian Cristian Iacob, Roland Toth, Stefan Sosnowski, Sandra Hirche

Linearity of Koopman operators and simplicity of their estimators coupled with model-reduction capabilities has lead to their great popularity in applications for learning dynamical systems.

Finite Dimensional Koopman Form of Polynomial Nonlinear Systems

no code implementations16 Jan 2023 Lucian Cristian Iacob, Maarten Schoukens, Roland Tóth

The Koopman framework is a popular approach to transform a finite dimensional nonlinear system into an infinite dimensional, but linear model through a lifting process, using so-called observable functions.

Koopman Form of Nonlinear Systems with Inputs

no code implementations25 Jul 2022 Lucian Cristian Iacob, Roland Tóth, Maarten Schoukens

In applications for systems with inputs, generally a linear time invariant (LTI) form of the Koopman model is assumed, as it facilitates the use of control techniques such as linear quadratic regulation and model predictive control.

Optimal Synthesis of LTI Koopman Models for Nonlinear Systems with Inputs

no code implementations15 Jun 2022 Lucian Cristian Iacob, Roland Tóth, Maarten Schoukens

In the lifted space, the dynamics are linear and represented by a so-called Koopman operator.

Deep Identification of Nonlinear Systems in Koopman Form

no code implementations6 Oct 2021 Lucian Cristian Iacob, Gerben Izaak Beintema, Maarten Schoukens, Roland Tóth
