Nonlinear system identification: A user-oriented road map

J Schoukens, L Ljung - IEEE Control Systems Magazine, 2019 - ieeexplore.ieee.org
Nonlinear system identification is an extremely broad topic, since every system that is not
linear is nonlinear. That makes it impossible to give a full overview of all aspects of the fi eld …

Identification of block-oriented nonlinear systems starting from linear approximations: A survey

M Schoukens, K Tiels - Automatica, 2017 - Elsevier
Block-oriented nonlinear models are popular in nonlinear system identification because of
their advantages of being simple to understand and easy to use. Many different identification …

Identification of nonlinear system composed of parallel coupling of Wiener and Hammerstein models

A Brouri, L Kadi, K Lahdachi - Asian Journal of Control, 2022 - Wiley Online Library
In this paper, a new method for the identification of nonlinear system composed by the
