Recursive Forward-Backward EDMD: Guaranteed Algebraic Search for Koopman Invariant Subspaces

IEEE Access
The implementation of the Koopman operator on digital computers often relies on the approximation of its action on finite-dimensional function spaces. This approximation is generally done by orthogonally projecting on the subspace.

Koopman-Based Model Predictive Control of Functional Electrical Stimulation for Ankle Dorsiflexion and Plantarflexion Assistance

IEEE Transactions on Neural Systems and Rehabilitation Engineering
Functional Electrical Stimulation (FES) can be an effective tool to augment paretic muscle function and restore normal ankle function. Our approach incorporates a real-time, data-driven Model Predictive Control (MPC) scheme built upon a Koopman operator ...

Contribution to the computation of regions of attraction of nonlinear systems based on the extended dynamic mode decomposition - Application to the anaerobic digestion

, 2021
El tema principal de la tesis es la identificación basada en datos de la región de atracción (ROA por sus siglas en ingles) de puntos de equilibrio asintóticamente estables. Aunque esta es la principal contribución computacional, la mayoría del trabajo de la tesis constituye en satisfacer las condiciones subyacentes para lograr aproximar la ROA\@. Para
