Abstract :
This paper addresses the problem of optimal H2 control by output feedback. Necessary and sufficient conditions concerning the existence of a linear stabilizing output feedback gain are provided in terms of the intersection of a convex set and a set defined by a nonlinear real valued function. The results can be easily extended to deal with linear uncertain systems, where uncertainties are supposed to belong to convex bounded domains, providing an H2 guaranteed cost output feedback control. Due to the geometrical properties of the above mentioned function, convex programming tools can be used for numerical purposes
