The robustness of a typical control scheme for Wiener systems is herein analyzed. Wiener systems consist of the cascade connection of a linear time invariant system and a static nonlinearity. Several approaches were reported in the literature in order to control this kind of systems. Most of these control schemes involve a transformation of the measured variable as well as the setpoint by using the inverse of the nonlinear gain.
