Structure-preserving Interpolatory Model Reduction for Port-Hamiltonian Differential-Algebraic Systems

Autor: Beattie, Chris A., Gugercin, Serkan, Mehrmann, Volker

We examine interpolatory model reduction methods that are well-suited for treating large scale port-Hamiltonian differential-algebraic systems in a way that is able to preserve and indeed, take advantage of the underlying structural features of the s

$\mathcal{H}_2$-gap model reduction for stabilizable and detectable systems

Autor: Breiten, Tobias, Beattie, Chris A., Gugercin, Serkan

We formulate here an approach to model reduction that is well-suited for linear time-invariant control systems that are stabilizable and detectable but may otherwise be unstable. We introduce a modified $\mathcal{H}_2$-error metric, the $\mathcal{H}_

Structure-preserving Model Reduction for Nonlinear Port-Hamiltonian Systems

Autor: Chaturantabut, Saifon, Beattie, Chris, Gugercin, Serkan

This paper presents a structure-preserving model reduction approach applicable to large-scale, nonlinear port-Hamiltonian systems. Structure preservation in the reduction step ensures the retention of port-Hamiltonian structure which, in turn, assure
