| Abstract: | The problem of
identification of a Wiener model is studied.The proposed identification method uses a
dynamic neural network (DANN) which consists of a linear dynamic neuron (LDN) in cascade
with a static BP neural network (SBP).A unified back-propagation algorithm is proposed to
estimate the weights and the biases of the LDN and the SBP simultaneously.Numerical
examples are provided to show the efficiency of the proposed method. |
