| 摘 要： | 针对一类具有输入与状态时滞的参数不确定非线性系统,基于T-S模糊模型,讨论该系统的保性能控制问题.通过构造状态反馈控制器,提出了在给定的性能指标和控制律下,闭环系统是二次保性能稳定的充分条件,并以线性矩阵不等式(LM I)的形式表示,数值算例显示该设计方法是有效的.

| Abstract: | Based on T-S fuzzy model,the guaranteed cost control problem of a class of uncertain nonlinear systems with input and state time delay is discussed.By constructing state-feedback controller,a sufficient condition that for the given performance index and control law,the closed-loop system is quadratic guaranteed cost stable is presented and expressed in terms of LMI.Numerical example shows the proposed design method is effective. |
