Study on Method for Identification of Hammerstein Model

A parameter identification method for SISO Hammerstein model was proposed.The basic idea is that the Hammerstein model can be converted to a class of intermediate model initially.Then,the estimates of the intermediate model parameters are obtained using an improved particle swarm optimization(IPSO) algorithm.Next,through the corresponding mathematics relations,the identification of the Hammerstein model is implemented.Finally,in numerical simulations,compared with using other identification methods,the feasibility of the presented method is illustrated.
