Abstract

A block oriented nonlinear system consists of a series of blocks. These blocks represent both memoryless nonlinearity and linear dynamics that comprise the overall input-output dynamics of system. Under this category, Hammerstein model is one of the block oriented model. The parameter identification method of Hammerstein model is proposed in this paper. The basic idea is that the nonlinear transfer function of the Hammerstein model can be changed to an intermediate model initially. Then, the parameters of the intermediate model are obtained via an improved particle swarm optimization algorithm. Next, through the relations of the parameters of the intermediate model and those of the Hammerstein model, the estimates of the parameters of the Hammerstein model are obtained. Finally, in simulation experiments, compared with other methods, the feasibility of the presented method is demonstrated.
