Stability preserving approximations of a semilinear hyperbolic gas transport model
Herbert Egger, Thomas Kugler, Björn Liljegren-Sailer
We consider the discretization of a semilinear damped wave equation arising, for instance, in the modeling of gas transport in pipeline networks. For time invariant boundary data,…

Input-tailored system-theoretic model order reduction for quadratic-bilinear systems
Björn Liljegren-Sailer, Nicole Marheineke
In this paper we suggest a moment matching method for quadratic-bilinear dynamical systems. Most system-theoretic reduction methods for nonlinear systems rely on multivariate frequ…
