Black box modelling of hard nonlinear behavior in the frequency domain
Jan Verspecht, Dominique Schreurs, André Barel, Bart K. J. C. Nauwelaers · 2002
A black box model is proposed to describe nonlinear devices in the frequency domain. The approach is based upon the use of describing functions and allows a better description of hard nonlinearities than an approach based upon the Volterra theory. Simulations and experiments are described illustrating the mathematical theory.
