| 摘 要： | 针对带有带宽约束的分布式网络化控制系统,研究了双层监控系统框架下的带有时延和丢包的子系统故障检测方法.针对带有状态时延、输入与输出存在丢包的子系统,将其建模为带有时延的马尔可夫跳跃系统,将故障检测的任务转化为选择适当的滤波器参数,保证扩展系统渐近稳定并满足一定的鲁棒性要求,根据滤波器参数获得系统的残差用于判断故障是否发...

| 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 als... |
