Convergence of the Iterative Rational Krylov Algorithm
Garret Flagg, Christopher Beattie, Serkan Gugercin
The Iterative Rational Krylov Algorithm (IRKA) of [8] is an interpolatory model reduction approach to the optimal approximation problem. Even though the method has…
Interpolatory H-infinity Model Reduction
Garret Flagg, Christopher Beattie, Serkan Gugercin
We introduce an interpolation framework for H-infinity model reduction founded on ideas originating in optimal-H2 interpolatory model reduction, realization theory, and complex Che…
Structure-preserving tangential interpolation for model reduction of port-Hamiltonian Systems
Serkan Gugercin, Rostyslav V. Polyuga, Christopher Beattie +1
Port-Hamiltonian systems result from port-based network modeling of physical systems and are an important example of passive state-space systems. In this paper, we develop the fram…
