利用参数化方法研究了一类具有状态时滞的离散切换系统在任意切换下的时滞相关H∞滤波问题。注意力集中在渐近稳定滤波器的设计，保证在H∞意义下的规定的噪声衰减水平。利用切换李雅普诺夫泛函，以线性矩阵不等式的形式给出了该问题可解的充分条件，其解构成了任意切换下的期望H∞滤波器.数值例子证明了所提出的技术的有效性。
In this paper, the problem of delay-dependent H∞filtering for a class of discrete-time switched systems with state delays is investigated under arbitrary switching using a parametrized approach. Attention is focused on the design of asymptotically stable filter guaranteeing a prescribed noise attenuation level in the H∞sense. By using switched Lyapunov functionals, sufficient conditions for the solvability of this problem are obtained in terms of linear matrix inequalities (LMIs), the solution of which constructs the desired H∞filter under arbitrary switching. Numerical examples are provided to demonstrate the effectiveness of the proposed techniques.
