Model order reduction by selective sensitivity

AIAA Journal, 1997
Summary: Many industrial structures are represented by models with a large number of degrees of freedom, thus making their use complex and costly. Model order reduction alleviates this problem by elaborating lower-dimensional models that satisfy some properties of the refined model.

Model Order Reduction using fractional order systems

2016 6th IEEE International Conference on Control System, Computing and Engineering (ICCSCE), 2016
In this work, a Model Order Reduction (MOR) technique is proposed to reduce the number of parameters required to describe a high dimensional integer system. Motivated by the fact a fractional order model is able to describe a large amount of system dynamics, the order reduction is achieved by expressing a given system as a product of fixed unknown ...

Interpolatory Model Order Reduction Method for Second Order Systems

Asian Journal of Control, 2017
AbstractIn this paper, we propose a structure‐preserving model reduction method for second‐order systems based onH2optimal interpolation. In the iterative process of the proposed method, an algorithm is presented for selecting interpolation points in order to control the dimension of the reduced system.

TLM Model Order Reduction

2004
The Finite-Difference Time-Domain (FDTD) method, Finite-Integration Technique (FIT) and the Transmission Line Matrix (TLM) method provide for discrete approximations of electromagnetic boundary value problems cast in state-space forms. The dimension of the generated state-space models is usually very large.

Introduction to Model Order Reduction

2008
In this first section we present a high level discussion on computational science, and the need for compact models of phenomena observed in nature and industry. We argue that much more complex problems can be addressed by making use of current computing technology and advanced algorithms, but that there is a need for model order reduction in order to ...

Advanced Topics in Model Order Reduction

2015
This chapter contains three advanced topics in model order reduction (MOR): nonlinear MOR, MOR for multi-terminals (or multi-ports) and finally an application in deriving a nonlinear macromodel covering phase shift when coupling oscillators. The sections are offered in a preferred order for reading, but can be read independently.

Parameter-dependent model order reduction

International Journal of Control, 1997
L In this paper we consider the optimal model reduction problem where the plant 2 model depends on parameters that are measurable. Such cases occur in many on-line as well as off-line applications and the question that arises is how to update the reduced order model without complete re-solution of the problem.

On symbolic model order reduction

IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems, 2006
Symbolic model order reduction (SMOR) is a macromodeling technique that generates reduced-order models while retaining the parameters in the original models. Such symbolic reduced-order models can be repeatedly simulated with a greater efficiency for varying model parameters.

Index-aware Model Order Reduction

2016
In this chapter, we discuss the index-aware model order reduction (IMOR) and its invariant the implicit-IMOR(IIMOR) method. We use the decoupled systems ( 3.2.11) and ( 3.7.1) to derive the IMOR and IIMOR method respectively.

Hierarchical Model-Order Reduction Flow

2010
This paper presents a hierarchical model-order reduction (HMOR) flow, where the linear parts of a hierarchically defined circuits are divided into independently reducable subcircuits. The impact of the hierarchical structure and circuit partitioning on two MOR methods is discussed and some simulation results are presented.
