We propose an extension of the Loewner framework to descriptor linear systems that
preserves the DAE (differential algebraic equation) structure of the underlying system. More …

Optimal Hankel norm model reduction for dynamical systems is of great significance in
model-based simulation and design. For the class of linear time-invariant systems, it is …

Hankel-norm approximation is a model reduction method for linear time-invariant systems,
which provides the best approximation in the Hankel semi-norm. In this paper, the …

Abstract The MORLAB (Model Order Reduction Laboratory) toolbox is a software solution in
MATLAB for the model reduction of linear time-invariant continuous-time systems. It contains …

In this thesis, we study a posteriori error estimation and adaptivity with the goal of automatic
model order reduction of large-scale systems. We propose efficient offline adaptive …

This paper discusses optimal Hankel norm approximations (HNA) of continuous-time
descriptor systems. The main results are based on the fact that the system can be …

The Hankel‐norm approximation of a linear time‐invariant system is a method of model
reduction which yields the best approximation in the Hankel semi‐norm. For the application …
