Abstract :
Fuzzy models of Takagi-Sugeno type enable representation of a wide class of nonlinear models. In this study we design a robust controller based fuzzy T-S system with structured uncertainties system in order to guarantee the closed loop stability and H∞ performance. The control and observer gains are given from LMI feasible solution. Sufficient stability conditions are established which make it possible to robustly stabilize the nonlinear systems with uncertainties. A numerical example is given to illustrate our result.
