Non-fragile H-infinite control for T-S fuzzy systems via LMI

This paper considers the problem of H/spl infin/ control for the nonlinear system described by the T-S fuzzy system under state feedback control gain perturbations based on the method of linear matrix inequality (LMI). The sufficient condition for the solutions to the problem is presented in terms of LMIS. A numerical example is provided to demonstrate the validity of the proposed design approach.
