Model Order Reduction for Nonlinear IC Models [PDF]

open access: yes, 2009
Model order reduction is a mathematical technique to transform nonlinear dynamical models into smaller ones, that are easier to analyze. In this paper we demonstrate how model order reduction can be applied to nonlinear electronic circuits. First we give an introduction to this important topic. For linear time-invariant systems there exist already some

A New Biased Model Order Reduction for Higher Order Interval Systems

open access: yesAdvances in Electrical and Electronic Engineering, 2016
This paper presents a new biased method for order reduction of linear continuous time interval systems. This method is based on the Stability equation method, Pade approximation and Kharitonov’s theorem. The higher order interval system is represented by

Scalable Symbolic Model Order Reduction [PDF]

open access: yes2008 IEEE International Behavioral Modeling and Simulation Workshop, 2008
Symbolic model order reduction (SMOR) is to reduce the complexity of a model with symbolic parameters. It is an important problem in analog circuit synthesis and digital circuit modeling with process variations. However, existing symbolic model order reduction (SMOR) methods do not scale well with the number of symbols or with the model order.

A Geometric Approach to Dynamical Model Order Reduction [PDF]

open access: yesSIAM Journal on Matrix Analysis and Applications, 2018
Any model order reduced dynamical system that evolves a modal decomposition to approximate the discretized solution of a stochastic PDE can be related to a vector field tangent to the manifold of fixed rank matrices. The Dynamically Orthogonal (DO) approximation is the canonical reduced order model for which the corresponding vector field is the ...

Model Order Reduction of Non-Linear Magnetostatic Problems Based on POD and DEI Methods [PDF]

open access: yes, 2014
In the domain of numerical computation, Model Order Reduction approaches are more and more frequently applied in mechanics and have shown their efficiency in terms of reduction of computation time and memory storage requirements. One of these approaches,

Model order reduction assisted by deep neural networks (ROM-net)

open access: yesAdvanced Modeling and Simulation in Engineering Sciences, 2020
In this paper, we propose a general framework for projection-based model order reduction assisted by deep neural networks. The proposed methodology, called ROM-net, consists in using deep learning techniques to adapt the reduced-order model to a ...

Model order reduction for nonlinear Schrödinger equation [PDF]

open access: yesApplied Mathematics and Computation, 2015
We apply the proper orthogonal decomposition (POD) to the nonlinear Schrödinger (NLS) equation to derive a reduced order model. The NLS equation is discretized in space by finite differences and is solved in time by structure preserving symplectic mid-point rule. A priori error estimates are derived for the POD reduced dynamical system.

Model order reduction applied to the numerical study of electrical motor based on POD method taking into account rotation movement [PDF]

open access: yes, 2014
In order to reduce the computation time and the memory resources required to solve an electromagnetic field problem, Model Order Reduction (MOR) approaches can be applied to reduce the size of the linear equation system obtained after discretisation.
