Adaptive Sampling for Structure Preserving Model Order Reduction of Port-Hamiltonian Systems
Paul Schwerdtner, Matthias Voigt
We present an adaptive sampling strategy for the optimization-based structure preserving model order reduction (MOR) algorithm developed in [Schwerdtner, P. and Voigt, M. (2020). S…
Balanced truncation model reduction for symmetric second order systems -- A passivity-based approach
Ines Dorschky, Timo Reis, Matthias Voigt
We introduce a model reduction approach for linear time-invariant second order systems based on positive real balanced truncation. Our method guarantees asymptotic stability and pa…
Discounted Cost Linear Quadratic Gaussian Control for Descriptor Systems
Hermann Mena, Lena-Maria Pfurtscheller, Matthias Voigt
We consider the linear quadratic Gaussian control problem with a discounted cost functional for descriptor systems on the infinite time horizon. Based on recent results from the de…
Semi-active damping optimization by adaptive interpolation
Zoran Tomljanović, Matthias Voigt
In this work we consider the problem of semi-active damping optimization of mechanical systems with fixed damper positions. Our goal is to compute a damping that is locally optimal…
