This paper presents a new concept of modeling of fractional-order nonlinear systems using a block-oriented Wiener model. The Wiener model uses two block covering a linear dynamics and a static nonlinearity. The dynamic model is described by fractional-order Orthonormal Basis Functions and the static nonlinearity by an artificial neural network.
