| 摘 要： | 讨论了一类具有时滞的不确定非线性系统的模糊H∞状态反馈控制问题。采用具有时滞和不确定项的Takagi-Sugeno(T-S)模糊模型对非线性系统进行建模，提出了一套基于LMI的模糊鲁棒控制器的系统设计方法，并给出了模糊H∞状态反馈控制器存在的充分条件，以保证闭环模糊系统渐近稳定并满足从干扰输入到输出控制输出的H∞范数界约束。示例仿真表明了该方法的有效性。

| Abstract: | This paper addresses the problem of the fuzzy H∞state feedback control for a class of uncertain nonlinear systems with time-delay. The Takagi-Sugeno (T-S) mo-del with time-delay and parameter uncertainties is adopted for modeling of nonlinear system. The systematic design procedure for the fuzzy robust controller based on linear matrix inequality (LMI) is given. Some sufficient conditions are derived for the existence of fuzzy H∞ state feedback controllers such that the closed-loop system is asymptotically stable and the effect of the disturbance input on controlled output is reduced to a prescribed level. An example is given to demonstrate the effectiveness of the proposed method. |
