Hermite kernel surrogates for the value function of high-dimensional nonlinear optimal control problems

Tobias Ehring, Bernard Haasdonk

Numerical methods for the optimal feedback control of high-dimensional dynamical systems typically suffer from the curse of dimensionality. In the current presentation, we devise a…

Improved a posteriori Error Bounds for Reduced port-Hamiltonian Systems

Johannes Rettberg, Dominik Wittwar, Patrick Buchfink +3

Projection-based model order reduction of dynamical systems usually introduces an error between the high-fidelity model and its counterpart of lower dimension. This unknown error c…

Randomized Symplectic Model Order Reduction for Hamiltonian Systems

Robin Herkert, Patrick Buchfink, Bernard Haasdonk +2

Simulations of large scale dynamical systems in multi-query or real-time contexts require efficient surrogate modelling techniques, as e.g. achieved via Model Order Reduction (MOR)…

Application of Deep Kernel Models for Certified and Adaptive RB-ML-ROM Surrogate Modeling

Tizian Wenzel, Bernard Haasdonk, Hendrik Kleikamp +2

In the framework of reduced basis methods, we recently introduced a new certified hierarchical and adaptive surrogate model, which can be used for efficient approximation of input-…

Symplectic Model Reduction of Hamiltonian Systems on Nonlinear Manifolds

Patrick Buchfink, Silke Glas, Bernard Haasdonk

Classical model reduction techniques project the governing equations onto linear subspaces of the high-dimensional state-space. For problems with slowly decaying Kolmogorov-n-width…
