File guidelines for benchmarks
Wiener-Hammerstein Benchmark
The data has been collected from an electronic circuit. First published in J. Schoukens, J. Suykens, L. Ljung. Wiener-Hammerstein Benchmark. 15th IFAC Symposium on System Identification (SYSID 2009), July 6-8, 2009, St. Malo, France
Input-Output measurements benchmark
These data sets have been first proposed in the paper "On the Estimation of Transfer Functions, Regularizations and Gaussian Processes - Revisited" by Tianshi Chen, Henrik Ohlsson, and Lennart Ljung, Automatica 48 (2012) 1525–1535, as benchmarks to test regularization methods.
Prof. Håkan Hjalmarsson has created a new repository for benchmarks in system identification ( The repository will be used to collect proposals for the invited session “System Identification Benchmarks”, 17th IFAC Symposium on System Identification, Beijing, China, 2015.
