Abstract :
A Wiener model with a series connection of a linear dynamic system followed by a static nonlinearity is proposed in this paper, based on extended MOESP (multivariable output-error state space) class of subspace model identification (SMI). Then a simple identification example is presented to validate the effectiveness of the algorithm.
