Impulse Response Estimation via Laguerre-Fourier Expansion
Tamás Dózsa, Art J. R. Pelling, Matthias Voigt
The empirical transfer function estimate (ETFE) is a widely used method for system identification of linear time-invariant (LTI) systems in engineering disciplines such as acoustic…
Towards an Efficient Shifted Cholesky QR for Applications in Model Order Reduction using pyMOR
Maximilian Bindhak, Art J. R. Pelling, Jens Saak
Many model order reduction (MOR) methods rely on the computation of an orthonormal basis of a subspace onto which the large full order model is projected. Numerically, this entails…
Adaptive Reduced Order Modelling of Discrete-Time Systems with Input-Output Dead Time
Art J. R. Pelling, Ennes Sarradj
While many acoustic systems are well-modelled by linear time-invariant dynamical systems, high-fidelity models often become computationally expensive due the complexity of dynamics…
Snapshot-driven Rational Interpolation of Parametric Systems
Art J. R. Pelling, Karim Cherifi, Ion Victor Gosea +1
Parametric data-driven modeling is relevant for many applications in which the model depends on parameters that can potentially vary in both space and time. In this paper, we prese…
