Identification of Wiener-Hammerstein model with multisegment piecewise-linear characteristic

This paper studies the identification of the wiener-Hammerstein model where the static nonlinearities are surrounded by two linear dynamic system. Therefore, we use a special form of nonlinearity representation `the multisegment piecewise-linear characteristic' and the half-substitution approach to linearize and to separate the model parameters. Hence, due to linearity in the model parameters, we use the recursive least squares.
