Properties of optimally robust controllers

Properties of optimally robust controllers

The robustness properties of controllers, which are optimally robust with respect to normalized coprime factor uncertainty, are analysed. It is shown that such optimally robust controllers admit perturbations which are, in size, larger than the robustness measure. It is shown how such perturbations...

description The robustness properties of controllers, which are optimally robust with respect to normalized coprime factor uncertainty, are analysed. It is shown that such optimally robust controllers admit perturbations which are, in size, larger than the robustness measure. It is shown how such perturbations can be constructed by solving Hankel norm approximation problems.
