Abstract

This paper addresses issues of stability analysis and H"~ control for a class of fuzzy time-delay descriptor systems described by an extended Takagi-Sugeno (T-S) fuzzy model. A delay-dependent stability criterion is first presented, and a H"~ control synthesis approach is then developed. Both the stability criterion and the H"~ controller synthesis are based on the solutions of linear matrix inequalities (LMIs). Finally, two examples are given to illustrate the effectiveness of the approaches proposed in this paper.
