| 英文摘要 |
| The problem of robust stabilization for a class of nonlinear systems, which is described as Takagi-Sugeno
(T–S) fuzzy model, is investigated through the use of fuzzy sampled-data control method. Firstly, by taking full advantage
of characteristic information on the whole sampling interval [tk; tk+1), a improved two-side time-dependent Lyapunov
functional is constructed. Furthermore, with the presented Lyapunov functional and free-matrix-based inequality, a robust
stabilization criterion is derived to guarantee the asymptotic stability for nonlinear systems, and the fuzzy sampled-data
controller design approach is also proposed. Finally, four simulation examples are given to verify the effectiveness and
superiority of the proposed method. |
