Rational approximation via selective modal analysis

G.C. Verghese, I.J. Pérez-Arriaga, F.C. Schweppe

We describe a recently developed framework for exploring the structure of linear time-invariant models of large systems, and for constructing interpretable or physically-based, reduced-order models that reproduce selected modes of the original systems to a desired accuracy. Application of this framework to constructing lumped approximations for interconnections of lumped and distributed systems is briefly explored.
