Coupled Electric Drives Data Set and Reference Models

Torbjörn Wigren and Maarten Schoukens

November 2017

The following report provides a description of the CE8 coupled electric drives laboratory process. A first set of continuous time model structures that are suitable to describe the nonlinear dynamics are presented. The data sets, which are available in .mat and .csv file formats, are then described in detail. The available data sets are short, which constitute a challenge when performing identification. In support of future work, Wiener models are identified with a recursive algorithm that is parameterized in continuous time. This approach reduces the number of parameters to four for identification of third order dynamics.
