This paper introduces new dilated LMI conditions for continuous-time linear systems which not only characterize stability and H2 performance specifications but also H performance specifications. These new conditions offer in addition to new analysis tools synthesis procedures that have the advantages of keeping the controller parameters independent of the Lyapunov matrix and offering supplementary degrees of freedom. The impact of such advantages is great on the multiobjective full-order dynamic output feedback control problem as the obtained dilated LMI conditions always encompass the standard ones. It follows that much less conservatism is possible in comparison to the currently used standard LMI based synthesis procedures. A numerical simulation based on an empirically abridged search procedure is presented and shows the advantage of the proposed synthesis methods. 1. Introduction The impact of linear matrix inequalities on the systems community has been so great that it dramatically changed forever the usually utilized
