这份报纸为联网的环境涉及柔韧的 H 过滤器问题，它随机服从于传播延期和包退学学生。由采用有 Bernoulli 分布拿 0 或 1 的价值的随机的系列，数据传播模型被获得。把扩大和随机的理论基于状态，为有 H 限制的柔韧的稳定性的足够的条件为过滤错误系统被导出。柔韧的过滤器以一某些线性矩阵不平等(LMI ) 的可行性被设计，它被采用矩阵一致转变形成。一个数字例子被给显示出建议过滤方法的有效性。

英文摘要：

This paper is concerned with the robust H ∞ filter problem for networked environments, which are subject to both transmission delay and packet dropouts randomly. By employing random series which have Bernoulli distributions taking value of 0 or 1, the data transmission model is obtained. Based on state augmentation and stochastic theory, the sufficient condition for robust stability with H ∞ constraints is derived for the filtering error system. The robust filter is designed in terms of feasibility of one certain linear matrix inequality （LMI）, which is formed by adopting matrix congruence transformations. A numerical example is given to show the effectiveness of the proposed filtering method.
