Identification of Hammerstein model: review and prospect
Hammerstein model is a typical nonlinear model consisting of the cascade structure of a static nonlinear element followed by a dynamic linear element.It represents a wide class of nonlinear processes.Considering immeasurable intermediate variables in the Hammerstein model,we survey the relevant theories and the synchronous method as well as the separate step method for identifying the static nonlinear element and the dynamic linear element.Then,we review the existing control system design schemes based on Hammerstein model.Finally,several opinions of the future research are given.
