摘要: 讨论了一类具有伊藤类型随机奇异T-S模糊系统有限时间鲁棒H∞控制问题.首先,针对含有界干扰的随机奇异系统,采用T-S模糊模型进行系统描述,同时给出了随机奇异T-S模糊系统有限时间随机稳定和有限时间鲁棒H∞控制问题的定义;然后,根据有限时间稳定性理论,构造Lyapunov-Krasovskii函数,通过对状态反馈系统的分析,利用线性矩阵不等式方法给出该系统的有限时间鲁棒H∞控制器有解的充分条件;最后,数值算例说明了该设计方法的有效性.

Abstract: Problems of finitetime stochastic stability and robust H∞ control for stochastic singular TakagiSugeno fuzzy systems with It type were investigated. Firstly, the stochastic singular system with bounded input noise was described by the TS fuzzy model. Meanwhile, definitions of finitetime stochastic stability and robust finitetime H∞ control of such systems were given. And then, based on the finitetime stability control theory, the sufficient condition for the existence of robust H∞ controller which could also satisfy finitetime stability was presented by analyzing a state feedback system. By constructing LyapunovKrasovskii function and applying linear matrix inequality, the description of a feasibility solution problem for the design of the controller was presented. Finally, numerical examples were given to illustrate the effectiveness of the obtained results.

Key words: stochastic singular TS fuzzy systems, robust H∞ control, finitetime stochastic stability, It differential, linear matrix inequality
