Distributed H2/H∞ Filtering for Hybrid Wired-wireless Networked Systems with Network-induced Delays and Packet Losses Constraints
摘要
Abstract
In distributed hybrid wired-wireless networked filtering systems, distributed sensors communicate with local fusion centers through the wireless network. The measured signals from sensors are then transmitted to gateways where they are converted to the corresponding wired network format, which are further transmitted to the filters through the wired network. This might suffer from distributed network-induced delays and packet losses of hybrid wired-wireless networks, making H2/H∞ filtering more difficult. To solve these problems, directed graph is firstly used to describe the communication topology of distributed sensor nodes, and different Markov chains and Bernoulli processes are employed to describe the characters of distributed network-induced delays and packet losses of hybrid wired-wireless networks, respectively. A general filtering error dynamic system model containing distributed filtering parameters and communication constraints of hybrid wired-wireless networks is then proposed. The designed filters enable the filtering error dynamic system to be stochastically stable and to achieve a prescribed H2/H∞ performance, and the relationships among the stochastic stability criteria, distributed filter parameters, maximum network-induced delays and packet losses of hybrid wired-wireless networks are further established. Finally, simulation results confirm the feasibility and effectiveness of the proposed method.关键词
