Medientyp: E-Artikel Titel: Efficient solution of large scale Lyapunov and Riccati equations arising in model order reduction problems Beteiligte: Saak, Jens; Benner, Peter Erschienen: Wiley, 2008 Erschienen in: PAMM, 8 (2008) 1, Seite 10085-10088 Sprache: Englisch DOI: 10.1002/pamm.200810085 ISSN: 1617-7061 Entstehung: Anmerkungen: Beschreibung: AbstractModel order reduction of large–scale linear time–invariant systems is an omnipresent task in control and simulation of complex dynamical processes. The solution of large scale Lyapunov and Riccati equations is a major task, e.g., in balanced truncation and related model order reduction methods, in particular when applied to semi–discretized partial differential equations constraint control problems. The software packageLyaPackhas shown to be a valuable tool in the task of solving these equations since its introduction in 2000.Here we want to discuss recent improvements and extensions of the underlying algorithms and their implementation.
