【Abstract】 A new identification method for the nonlinear systems of Wiener type is proposed. The model of nonlinear systems of Wiener type is made up of Laguerre function networks with static BP (SBP) networks, and also, its recursive identification algorithm is given. The parameter identification of this model needs no a priori knowledge on the order degree and the time delay of the identified nonlinear systems. The digital simulation result shows the efficiency of the proposed method.更多还原
