Estimating Dispersion Curves from Frequency Response Functions via Vector-Fitting
Mohammad I. Albakri, Vijaya V. N. Sriram Malladi, Serkan Gugercin +1
Driven by the need for describing and understanding wave propagation in structural materials and components, several analytical, numerical, and experimental techniques have been de…
Sampling-free parametric model reduction for structured systems
Christopher Beattie, Serkan Gugercin, Zoran Tomljanovic
We consider the reduction of parametric families of linear dynamical systems having an affine parameter dependence that differ from one another by a low-rank variation in the state…
Revisiting IRKA: Connections with pole placement and backward stability
C. Beattie, Z. Drmac, S. Gugercin
The iterative rational Krylov algorithm (\textsf{IRKA}) is a popular approach for producing locally optimal reduced-order -approximations to linear time-invariant (L…
Structure-preserving Interpolatory Model Reduction for Port-Hamiltonian Differential-Algebraic Systems
Chris A. Beattie, Serkan Gugercin, Volker Mehrmann
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…
-gap model reduction for stabilizable and detectable systems
Tobias Breiten, Chris A. Beattie, Serkan Gugercin
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. W…
