A preliminary look at the self-study kit for dissemination of nonlinear system identification

Practitioners in industry often face nonlinear systems but nevertheless use Linear Time Invariant (LTI) identification due to restricted dissemination of nonlinear identification knowledge. Being aware that most systems can behave nonlinearly, there is a need for a more widespread knowledge about the nonlinear system identification (SI) in general and the NL detection in particular. The goal of this work is to create a self-study kit to introduce this knowledge to the practitioner in a practical and self-contained way. The focus is put to obtaining useful, intuitive, and usable hands-on knowledge of nonlinear SI. To this end, every step is applied to a small practical but real test case system in order to keep the gap between theory and practice very small. A small mechanical test case system is already built to support the self-study kit. The self-study kit will support more than a linear learning process to allow users, with different background knowledge, learn nonlinear SI. It will be created in a cross-linked modular way. This allows a user without previous knowledge to learn the identification process step by step, while an experienced user will be able to cherry-pick the knowledge required without wasting too much time on searching information.
