  A key step in control of precision mechatronic systems is Frequency Response
Function (FRF) identification. The aim of this paper is to illustrate relevant
developments and solutions for FRF identification for advanced motion control.
Specifically dealing with transient and/or closed-loop conditions that can
normally lead to inaccurate estimation results. This yields essential insights
for FRF identification for advanced motion control that are illustrated through
a simulation study and validated on an experimental setup.
