The problem covers the bounded real, positive realand sector-bounded performance as a special case by choosing the corresponding

quadratic supply rate. Moreover, we also prove necessary

and sufficient conditions to state feedback controllers ensuring quadratic stability for Takagi-Sugeno fuzzy systems in theory. But our main objective is to generate a family of linear matrix inequalities based on an extension of P´olya’s theorem(a.k.a Matrix-valued P´olya’s heorem).

The proposed conditions are stated as progressively less conservative sets of linear matrix inequalities, allowing us to obtain a solution for the quadratic stabilizability problem whenever a solution exists.Table of Content 論文摘要I
