Silverbox System

The Silverbox system can be seen as an electronic implementation of the Duffing oscillator. It is build as a 2nd order linear time-invariant system with a 3rd degree polynomial static nonlinearity around it in feedback. This type of dynamics are, for instance, often encountered in mechanical systems.

The provided data is part of a previously published ECC paper available online. A technical note describing the Silverbox benchmark can be found here. All the provided data (.mat file format) on the Silverbox system is available for download here. This .zip file contains the Silverbox dataset as specified in the benchmark document (V1 is the input record, while V2 is the measured output), extended with a .csv version of the same data and an extra data record containing a Schroeder phase multisine measurement. 

Previously published results on the Silverbox benchmark can be found here and below. You can submit your own results through this form. Note that the reported results are curated, only complete submissions with meaningful contributions will be included. Candidate entries should make use of the Python dataloader functionalities and figure of merit calculation functions provided through this link. 

Special thanks to Johan Schoukens for creating this benchmark, and to Torbjörn Wigren for hosting this benchmark.
