| 中文摘要 |
| 针对数据包在网络中传输的一步随机时延情形, 研究任意切换律作用下的离散切换系统的H∞滤波问题. 时延数据包包含系统的测量输出信号和切换信号, 其时延由一个满足Bernoulli分布的随机变量来描述. 选用切换Lyapunov函数, 设计全阶和降阶的切换滤波器使得滤波误差系统在均方意义下指数稳定且具有扰动衰减度γ. 滤波器的参数通过求解一组线性矩阵不等式获得. 数值仿真表明了所提出设计方法的有效性.

| 英文摘要 |
| To deal with random communication time-delays, the H-Infinity filtering problem is investigated for a class of discrete-time switched systems with arbitrary switching laws. The delayed data packets include the measured output and the switched signal; and the delay-time satisfies the Bernoulli random binary distribution. By using the switched Lyapunov function, we obtain the full and reduced-order switched filters. The systems of filtering errors are exponentially mean-square stable and satisfy the prescribed H-Infinity performance constraint. The filter parameters can be obtained by solving a set of linear matrix inequalities(LMIs). Finally, a numerical example is provided to illustrate the application of the proposed design method. |
