Laguerre-svd Reduced Order Modeling
A reduced order modeling method based on a system description in terms of orthonormal Laguerre functions, together with a Krylov subspace decomposition technique is presented. The link with Padé approximation, the block Arnoldi process and singular value decomposition (SVD) leads to a simple and stable implementation of the algorithm. Novel features of the approach include the determination of ...
متن کاملStable Laguerre-svd Reduced Order Modeling
A provably stable reduced order model, based on a projection onto a scaled orthonormal Laguerre basis, followed by a SVD step, is proposed. The method relies on the conformal mapping properties induced by the complete orthonormal scaled Laguerre basis, allowing a mapping from the discrete-stable case to the continuous-stable case and vice versa.
متن کاملPassive Reduced Order Multiport Modeling: The Padé-Laguerre, Krylov-Arnoldi-SVD Connection
A reduced order multiport modeling algorithm based on the decomposition of the system transfer matrix into orthogonal scaled Laguerre functions is proposed. The link with Padé approximation, the block Arnoldi method and singular value decomposition leads to a simple and stable implementation of the algorithm.

In this contribution we first briefly introduce a new Reduced Order Modelling (ROM) algorithm based on the decomposition of the system transfer matrix into orthogonal scaled Laguerre functions. This new technique overcomes the difficulty of unstabilities at low frequencies often experienced with other ROM techniques. Next, we propose a new approach to automatically derive subcell models for 2D ...
متن کاملReduced order modelling of RLC-networks using an SVD- Laguerre based method
With interconnect increasingly contributing to the electrical behaviour of integrated circuits, both by higher frequencies and smaller dimensions, it becomes increasingly important to incorporate its behaviour into simulations of ICs. This can be done rather elegantly by summarizing interconnect behaviour into a compact or reduced order model which is then co-simulated with the circuit. A simil...
