Resumen:
As reported in the literature,Wiener models have emerge as an appealing proposal for nonlinear processes representation due to their simplicity and the property of being valid over a larger operating region than a LTI model.
In this article, we propose a methodology to analyzed the robustness of a typical control scheme. To perform this analysis, we use a parametric description for the Wiener system. This model allows to describe the uncertainty as a set of parameters for the linear and the nonlinear blocks. Then, the linear block uncertainty is considered as a parameter-affine-dependent model and the nonlinear block uncertainty is studied as a conic-sector. The robustness analysis is then performed using µ-theory.
