Mixed H/sub 2//H/sub /spl infin// control design for fuzzy dynamic systems via LMI

This paper addresses the mixed H/sub 2//H/sub /spl infin// control of complex nonlinear systems which can be represented by a fuzzy dynamic model. Two kinds of new control design methods are proposed. The closed-loop fuzzy control system is asymptotically stable and satisfies the mixed H/sub 2//H/sub /spl infin// performance. The controller can be obtained by linear matrix inequality (LMI) techniques.
