Abstract

An overview of model-order-reduction methods for descriptor control system is presented, with the emphasis on the Krylov-subspace-based methods. We used two standard benchmark descriptor problems for an empirical comparison of the methods. The results indicate that the methods perform differently, depending on whether they are used on generalized control systems or on standard control systems.
