Abstract
This paper proposes a method to estimate the non-parametric frequency- response functions of the linear parts of a Wiener-Hammerstein model u sing specially designed periodic excitation signals. Weak assumptions are made concerning the static nonlinearity. The estimator is develope d within a stochastic errors-in-variables framework. The applicability of the method is illustrated using simulations. (C) 1997 Elsevier Sci ence Ltd.
