Abstract

This paper is devoted to the problem of designing robust H₂ controllers for linear uncertain systems based on state observers. Exploiting the famous separation principle, sufficient conditions for the existence of controllers and an upper bound on H₂ performance are obtained. Observer matrix gains which make the upper bound minimized are also derived by the methods of convex optimization based on linear matrix inequalities.
