Abstract:In this paper, the Takagi-Sugeno (T-S) fuzzy model with multiplicative noises is used to represent the complex nonlinear stochastic system. For practical applications, disturbance attenuation performance is also important issues in controlled systems except for stability. Furthermore, robust control problem is also studied for the T-S fuzzy models with uncertainties. Simultaneously, delay-dependent stability criterion is proposed for the time-delay T-S fuzzy models. Besides, under unmeasurable conditions, the design problem for observer-based fuzzy controller is also discussed and solved in this paper. Based on the proposed stability criteria, one can find that the closed-loop nonlinear stochastic systems driven by designed passive fuzzy controller is asymptotically stable and passive in the mean square.
