A Unified Approach for the Identification of Wiener, Hammerstein, and Wiener–Hammerstein Models by Using WH-EA and Multistep Signals

Table 3

Ranking of estimated linear models for numerical example 1 (Wiener system). Models 4p, 2z/5p, 3z/5p, and 4z/5p have been excluded due to their high MCL values.
