英文摘要 |
This paper considers the stabilization problem of a class of T–S model-based interval type--2 stochastic fuzzy systems. The objective is to design a state feedback fuzzy controller such that the closed-loop system is stochastically asymptotically stable. Sufficiency conditions of stochastic stability for the systems are established by using the stochastic Lyapunov approach. Considering the properties of the interval type--2 membership functions, we introduce some slack matrices in order to derive a less conservative result. Finally, two simulation examples are given to illustrate the advantages and effectiveness of the proposed method. |
