Robust disk pole assignment by state and output feedback for generalised uncertainty models

We propose control synthesis algorithms for robust disk pole assignment in the case of generalised uncertainty models. Using LMIs we obtain easy to use methods that handle a great variety of uncertainty modellings. The generalised uncertainty approach is a new promising way to consider almost any state-space uncertain model. The results of the paper are given by necessary and sufficient formulas for quadratic d-stabilisability via state and output feedback. An illustrative numerical example is treated
