ESTIMATING GRAMIANS OF LARGE-SCALE TIME-VARYING SYSTEMS
Younes Chahlaoui,* Paul Van Dooren*
* Université catholique de Louvain, Belgium
In this paper we present a Smith-like updating technique to estimate a low rank approximation of the Gramians of a time-varying system. We obtain error estimates of our approximation and also explain how to use this for model reduction of time-varying systems.
Keywords: Model reduction, time-varying systems, Gramians
