Error Estimation for Arnoldi-based Model Order REduction of MEMS

Bechtold T., Rudnyi E.B., Korvink J.G., University of Freiburg, Germany, DE

In this paper we present a heuristic error estimation for the Pade-type approximation of transfer function via Arnoldi algorithm. We suggest using the solution of the Lyapunov equations for reduced-order systems as a stop-criterion in [...]

Krylov-Subspace-Based Order Reduction Methods Applied to Generate Compact Thermo-Electric Models for MEMS

Bechtold T., Salimbahrami B., Rudnyi E.B., Lohmann B., Korvink J.G., IMTEK, University of Freiburg, DE

A high power dissipation density in todays miniature electronic/mechanical systems makes on-chip thermal management very important. In order to achieve quick to evaluate, yet accurate thermo-electric models, needed for the thermal management of microsystems, a [...]
