AB  - Non linear systems identification is a widespread topic and many techniques have been developed over the years in order to identify or synthesize black box models. Among the others, Wiener and Hammerstein structures are two of the more common nonlinear models, and identification techniques based on them are widespread in the literature. The choice of one structure over the other needs some a-priori knowledge. In this paper a novel method to determine if a system has a Wiener or Hammerstein nature is introduced. The method is based on the comparison of frequency responses in linear and nonlinear working region. Some simulated and real test results are reported in order to confirm the validity of the proposed approach.
