Stabilized model reduction for nonlinear dynamical systems through a contractivity-preserving framework

Autor: Chaturantabut Saifon

Publikováno v: International Journal of Applied Mathematics and Computer Science, Vol 30, Iss 4, Pp 615-628 (2020)

This work develops a technique for constructing a reduced-order system that not only has low computational complexity, but also maintains the stability of the original nonlinear dynamical system. The proposed framework is designed to preserve the con

Structure-preserving Model Reduction for Nonlinear Port-Hamiltonian Systems

Autor: Chaturantabut, Saifon, Beattie, Chris, Gugercin, Serkan

This paper presents a structure-preserving model reduction approach applicable to large-scale, nonlinear port-Hamiltonian systems. Structure preservation in the reduction step ensures the retention of port-Hamiltonian structure which, in turn, assure

Nonlinear Parametric Inversion using Interpolatory Model Reduction

Autor: de Sturler, Eric, Gugercin, Serkan, Kilmer, Misha E., Chaturantabut, Saifon, Beattie, Christopher, O'Connell, Meghan

Publikováno v: SIAM Journal on Scientific Computing, Vol. 37, Issue: 3, B495--B517, 2015

Nonlinear parametric inverse problems appear in several prominent applications; one such application is Diffuse Optical Tomography (DOT) in medical image reconstruction. Such inverse problems present huge computational challenges, mostly due to the n
