On the stability of Krylov-based order reduction using invariance properties of the controllability subspace
نویسندگان
چکیده
This article presents an algorithm to achieve stable reduced models using Krylov-based model order reduction for discrete time systems while matching a certain number of Markov parameters. By using the invariance properties of the controllability matrix suitable input and output Krylov subspaces are derived. The method is illustrated performing model reduction of four well-known benchmark problems.

Model Reduction for Time-Varying Descriptor Systems Using Krylov-Subspaces Projection Techniques
We will present a projection approach for model reduction of linear time-varying descriptor systems based on earlier ideas in the work of Philips and others. The idea behind the proposed procedure is based on a multipoint rational approximation of the monodromy matrix of the corresponding differential-algebraic equation. This is realized by orthogonal projection onto a rational Krylov subspace....

متن کاملMoment Matching Theorems for Dimension Reduction of Higher-Order Dynamical Systems via Higher-Order Krylov Subspaces
Moment matching theorems for Krylov subspace based model reduction of higherorder linear dynamical systems are presented in the context of higher-order Krylov subspaces. We introduce the definition of a nth-order Krylov subspace Kn k ({Ai} n i=1;u) based on a sequence of n square matrices {Ai}i=1 and vector u. This subspace is a generalization of Krylov subspaces for higher-order systems, incor...
متن کاملKrylov Subspace Methods in Linear Model Order Reduction: Introduction and Invariance Properties
In recent years, Krylov subspace methods have become popular tools for computing reduced order models of high order linear time invariant systems. The reduction can be done by applying a projection from high order to lower order space using bases of some subspaces called input and output Krylov subspaces. One aim of this paper is describing the invariancies of reduced order models using these m...
متن کاملA Novel Noise Reduction Method Based on Subspace Division
This article presents a new subspace-based technique for reducing the noise of signals in time-series. In the proposed approach, the signal is initially represented as a data matrix. Then using Singular Value Decomposition (SVD), noisy data matrix is divided into signal subspace and noise subspace. In this subspace division, each derivative of the singular values with respect to rank order is u...
