摘要
研究了连续T-S模糊系统H∞状态反馈控制器的设计问题.主要目的是针对连续T-S模糊系统设计H∞状态反馈控制器,使得闭环控制系统渐近稳定并且满足给定的H∞性能指标.通过应用积分型模糊Lyapunov函数方法并结合有效的矩阵变换技术引入松弛变量,以线性矩阵不等式的形式给出了两个H∞状态反馈控制器存在的充分条件.最后通过仿真算例验证了所提出方法的有效性.
This paper investigates the deign problem of H∞state feedback controller for continuous-time T-S fuzzy systems.Attention is focused on the design of a H∞state feedback controller such that the closed-loop control system is asymptotically stable with a prescribed H∞performance.By using integral type fuzzy Lyapunov function and introducing slack variables,two sufficient conditions for the existence of such H∞state feedback controller are proposed in terms of linear matrix inequalities.Finally,a numerical example is provided to demonstrate the effectiveness of the proposed design approaches.
