摘要
本文设计了一种带马尔科夫跳变的中立型混合时滞系统的H∞滤波器,目的是将分布时滞和马尔科夫跳引入中立型时滞系统。利用Lyapunov稳定理论,构造了新的L-K(Lyapunov-Krasovskii)泛函,用积分不等式方法并结合线性矩阵不等式技术,使得具有马尔科夫跳的中立型时滞系统的滤波误差系统满足一定的渐进稳定条件。在保证H∞范数小于一定的性能指标条件下,得到H∞滤波存在的一些充分条件,通过数值仿真得到滤波器的误差图。
A filter for a neutral distributed delay system with Markov transitions is mainly designed.The purpose is to introduce distributed variable delays and Markov jumps into neutral delay systems.Using the Lyapunov stability theory,a new LK(Lyapunov-Krasovskii)functional is constructed.The integral inequality method is combined with the linear matrix inequality technology to make the filtering error system of a Markov-jumped neutral time-delay system satisfies certain asymptotic stability conditions.Under the condition that the norm is less than a certain performance index,some sufficient conditions for filtering exist,and the error of the filter is obtained through numerical simulation.
