Regularization method for calibrated POD reduced-order models

open access: yesMATEC Web of Conferences, 2014
In this work we present a regularization method to improve the accuracy of reduced-order models based on Proper Orthogonal Decomposition. The bench mark configuration retained corresponds to a case of relatively simple dynamics: a two-dimensional flow ...

A parametric macromodelling technique [PDF]

open access: yes, 2009
With the ever growing complexity of high-frequency systems in the electronic industry, formation of reduced-order models or compact macromodels of these systems is paramount.

Generative adversarial reduced order modelling

open access: yesScientific Reports
AbstractIn this work, we present GAROM, a new approach for reduced order modeling (ROM) based on generative adversarial networks (GANs). GANs attempt to learn to generate data with the same statistics of the underlying distribution of a dataset, using two neural networks, namely discriminator and generator.

Determining Reduced Order Models for Optimal Stochastic Reduced Order Models

open access: yes, 2015
The use of parameterized reduced order models(PROMs) within the stochastic reduced order model (SROM) framework is a logical progression for both methods. In this report, five different parameterized reduced order models are selected and critiqued against the other models along with truth model for the example of the Brake-Reuss beam. The models are: a

Reduced Order Modeling of an Industrial Feeder Model

open access: yesIFAC Proceedings Volumes, 2003
Models of glaes furnaces are described by a set of nonlinear partial differential equâtioris which govern the mass, momentum and energy balances and a numberof non-linear functions of the independent scalais which describe the dependent variables like viscosities and densities in a fluid.

New Regularization Method for Calibrated POD Reduced-Order Models

open access: yesMathematical Modelling and Analysis, 2016
Reduced-order models based on Proper orthogonal decomposition are known to suffer from a lack of accuracy due to the truncation effect introduced by keeping only the most energetic modes.

Characteristics of linear modal instabilities in hypersonic flows with detached shock waves

open access: yesResults in Engineering, 2021
A preliminary study on the linear instabilities present in a defined hypersonic flow over a blunt object is analyzed in this work. Such flow instabilities are defined in the detached shock wave and the defined shock region between the shock wave and the ...

Reduced order models based on pod method for schrödinger equations

open access: yesMathematical Modelling and Analysis, 2013
Reduced-order models (ROM) are developed using the proper orthogonal decomposition (POD) for one dimensional linear and nonlinear Schrödinger equations. The main aim of this paper is to study the accuracy and robustness of the ROM approximations.

Linear Reduced-Order Model Predictive Control

open access: yesIEEE Transactions on Automatic Control, 2022
Model predictive controllers use dynamics models to solve constrained optimal control problems. However, computational requirements for real-time control have limited their use to systems with low-dimensional models. Nevertheless, high-dimensional models arise in many settings, for example discretization methods for generating finite-dimensional ...
