Model reduction of descriptor systems by interpolatory projection methods
(Siam Publications, 2013)
In this paper, we investigate an interpolatory projection framework for model reduction of descriptor systems. With a simple numerical example, we first illustrate that directly applying the subspace conditions from the ...
Interpolatory projection methods for parameterized model reduction
(Siam Publications, 2011)
We provide a unifying projection-based framework for structure-preserving interpolatory model reduction of parameterized linear dynamical systems, i.e., systems having a structured dependence on parameters that we wish to ...
H-2 model reduction for large-scale linear dynamical systems
(Siam Publications, 2008)
The optimal H-2 model reduction problem is of great importance in the area of dynamical systems and simulation. In the literature, two independent frameworks have evolved focusing either on solution of Lyapunov equations ...
Recycling BICG with an application to model reduction
(Siam Publications, 2012)
Science and engineering problems frequently require solving a sequence of dual linear systems. Besides having to store only a few Lanczos vectors, using the biconjugate gradient method (BiCG) to solve dual linear systems ...
