Order reduction of large scale DAE models
A tool for the order reduction of differential algebraic equations (DAEs) is outlined in this report. Through the use of an equation dependency analysis and nonlinear function approximation, the algebraic equations can be divided into sets that require implicit or explicit solutions. If all of the algebraic variables can be solved or approximated explicitly, the DAE becomes a set of ordinary di...
متن کاملOrder Reduction of (Truly) Large-Scale Linear Dynamical Systems
In recent years, Krylov subspace methods have become widely-used tools for order reduction of large-scale linear dynamical systems; see [1] for a recent survey of such reduction techniques. Despite all the progress in this area, the development of algorithms that are applicable to truly large-scale systems and at the same time preserve the key structures of the large-scale system remains a chal...
متن کاملLarge-Scale Linear Systems from Order-Reduction (Benchmark Proposal)
This benchmark suite is composed of nine examples of large-scale linear systems, ranging in dimensionality in the tens to the low thousands. The benchmarks are derived from diverse fields such as civil engineering and robotics, and are based on similar existing test sets for model-order reduction algorithms in control and numerical analysis. Each example is provided in the SpaceEx XML model for...
متن کاملModel Order Reduction for Large Scale Finite Element Engineering Models
Software MOR for ANSYS has been developed at IMTEK in 2003. It allows us to perform model reduction directly to finite element models developed in ANSYS. The goal of the present paper is to describe progress achieved for the last two years and review our publications with application of MOR for ANSYS to various engineering problems for different domains: heat transfer, structural mechanics, the...
متن کاملLarge Scale Linear MIMO System Model Order Reduction using Artificial Bee Colony Optimization Algorithm
In this paper, a computationally simple approach is proposed for order reduction of large scale linear dynamic MIMO (Multi input-Multi output) system using Artificial Bee Colony (ABC) optimization algorithm. The method is based on minimization of the Integral square error (ISE) between the transient responses of original and reduced order models pertaining to unit step input. The reduction proc...
