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.
Nonlinear system identification benchmark
The linked web site hosts a number of nonlinear system identification datasets
