Factorization of Nonlinear Systems [PDF]

, 1989
Summary: A basic result of \textit{H. Bart}, \textit{I. Gohberg} and \textit{M. A. Kaashoek} [Minimal factorization of matrix and operator functions (1979; Zbl 0424.47001)] parametrizes factorizations of the transfer function of a linear system in terms of the state space equations of the system. This paper extends their result to nonlinear systems.

Extremum Seeking for the First Derivative of Nonlinear Maps with Constant Delays via a Time-Delay Approach

Mathematics
This paper introduces an extremum seeking (ES) scheme for the unknown map’s first derivative by tailoring a demodulation signal in which the closed-loop system is subject to constant transmission delays.

A Simplified Laminar Flow Model for the Pultrusion of Glass Fiber/Polyethylene Terephthalate Commingled Yarns

Advanced Engineering Materials, EarlyView.
A simplified thermoplastic pultrusion model is developed to predict thermal fields in glass fiber/polyethylene terephthalate (GF/PET) composites with reduced computational cost. By combining effective material homogenization, validation against literature data, and Gaussian‐process‐based optimization, the study reveals how heating limits, pulling speed,
