摘要
研究一类T-S模糊模型描述的非线性时滞系统的H∞控制问题.基于一种新的时滞独立稳定性准则,分别给出了经状态反馈和基于模糊观测器的输出反馈对系统进行H∞控制的方法.基于线性矩阵不等式的可解性,给出了H∞控制器存在的充分条件.仿真例子验证了所提出方法的有效性.
The problem of H∞ control for nonlinear systems with time delay described by T-S fuzzy model is studied. Based on a new delay-independent stability criterion, the design scheme of H∞ controller via state feedback is obtained. Furthermore, an observer-based H∞ controller is also addressed. Based on the feasible solutions of linear matrix inequalities (LMIs), some sufficient conditions for the existence of H∞ controller are developed. Simulation example shows the effectiveness of the proposed methods.
