Hierarchical estimation method for fractional-order systems based on the auxiliary model

•A hierarchical least squares algorithm is proposed to study the identification of the fractional Hammerstein-Wiener system.•Using the hierarchical identification principle, the whole identification process is decomposed into several stages to estimate the parameters of the system.•To handle immeasu...
