摘要:
Delta算子的方法设计了一类滤波器.传感器至控制器和控制器到执行器的两个信道中都存在数据包丢失的现象，由两个独立的伯努利分布的白色序列表示.混合随机时延由网络诱导时延和离散无限分布时延组成.利用马尔科夫随机过程建立了一个网络，构造李雅普诺夫-卡拉索夫斯基函数，在线性矩阵不等式（LMI）性能的滤波误差系统随机稳定的充分条件，设计滤波器并得到了滤波器参数.数值计算例证了该方法的有效性
Abstract:
In this paper, the problem offiltering for networked control systems using delta operator is investigated, which includes two-channel packet dropouts and mixed random delays. Random communication packet dropouts exist in both channels from sensors to controllers and from controllers to actuators. They are represented by two independent Bernoulli distributed white sequences. The mixed random time-delays consist of network induced time delay and discrete infinite distributed delays. A networked-based model is considered with a Markov stochastic process and thefiltering error system is constructed by using Lyapunov-Krasovskii functional in delta domain. A sufficient condition for stochastic stability of the filtering error system with anperformance is obtained in terms of linear matrix inequalities (LMI). The explicit expression of the desiredfilter is given. A numerical example shows the effectiveness of the proposed method.
