带有时延和丢包的分布式网络化控制系统故障检测方法
Fault detection of distributed networked control systems with multiple delays and packet loss
摘要
Abstract
In order to deal with the limited bandwidth of the network, two-level DNCS (distributed networked control systems) is presented and subsystem fault detection unit is designed for DNCS with multiple delay and packet loss. Based on the impact analysis of packet loss on the system, the subsystems with multiple delays, input and output packet loss are modeled as Markovian jump system. The fault detection filter design problem is transformed to find the filter parameters such that the extended system is stable and also is satisfied with the robust condition. The residual obtained by the robust filter is used to judge whether a fault would happen. Finally the simulations are presented and discussed.关键词
