Can Hinfstruct be used with real parametric uncertainty?

I have a plant with real parametric uncertainty. In the Matlab documentation of the Robust Control Toolbox it is stated that in the presence of uncertainty musyn-command should be used. However, in multiple research papers hinfstruct is used for plants with parametric uncertainty. So my question is can hinfstruct handle umcertain plants?

Hi Adel,

"hinfstruct" can handle plants with parametric uncertainty by designing a controller that works well for the nominal case and nearby uncertainties, it does not provide the same level of robustness guarantees as "musyn", which is designed to optimize for the worst-case scenario across the full range of uncertainties. Researchers may use "hinfstruct" in papers for various reasons, such as simplicity, computational efficiency, or because the robustness provided by the local optimization is sufficient for their specific application.
