摘要：
Through free-weighting matrix and relaxed LMI approach, this paper deals with the problem of robust H. control for uncertain discrete stochastic fuzzy systems with interval time-varying delays. The uncertainties are timevarying but norm-bounded. The purpose is to design a state feedback fuzzy controller such that the resulting closed-loop system is not only robustly stochastically stable but also with a disturbance attenuation level gamma. Based on Takagi-Sugeno (T-S) fuzzy model, a delay-dependent sufficient condition for the solvability of the problem is obtained by utilizing a proper Lyapunov functional.
