Linear port-Hamiltonian DAE systems revisited
Arjan van der Schaft, Volker Mehrmann
Port-Hamiltonian systems theory provides a systematic methodology for the modeling, simulation and control of multi-physics systems. The incorporation of algebraic constraints has…
Discretization of inherent ODEs and the geometric integration of DAEs with symmetries
Peter Kunkel, Volker Mehrmann
Discretization methods for differential-algebraic equations (DAEs) are considered that are based on the integration of an associated inherent ordinary differential equation (ODE).…
A Lagrange subspace approach to dissipation inequalities
Arjan van der Schaft, Volker Mehrmann
The standard dissipation inequality for passivity is extended from storage functions to general Lagrange subspaces. This is shown to have some interesting consequences. A classical…
Local and global canonical forms for differential-algebraic equations with symmetries
Peter Kunkel, Volker Mehrmann
Linear time-varying differential-algebraic equations with symmetries are studied. The structures that we address are self-adjoint and skew-adjoint systems. Local and global canonic…
Error Analysis of a Model Order Reduction Framework for Financial Risk Analysis
Andreas Binder, Onkar Jadhav, Volker Mehrmann
A parametric model order reduction (MOR) approach for simulating the high dimensional models arising in financial risk analysis is proposed on the basis of the proper orthogonal de…
Computation of the nearest structured matrix triplet with common null space
Nicola Guglielmi, Volker Mehrmann
We study computational methods for computing the distance to singularity, the distance to the nearest high index problem, and the distance to instability for linear differential-al…
