| 摘 要： | 研究了一类网络控制系统丢包情况下传感器输出饱和的故障检测问题.首先假设网络控制系统丢包存在于传感器到控制器之间,并用两个独立的伯努利分布序列来描述.然后在传感器输出饱和约束条件下设计了一个故障检测观测器,用来加大故障对残差的敏感性并减小干扰对故障的影响.最后基于线性矩阵不等式技术,得到一个鲁棒故障检测系统有界均方稳定的充分条件,并满足了H∞性能指标.数值算例表明了在丢包和传感器饱和约束情况下所提方法的有效性.

| Abstract: | The fault detection problem was considered for a class of networked control systems with packet dropout subject to sensor saturation.The packet dropout was assumed to be exist in the sensor-to-controller link,and two independent Bernoulli distributed white sequences were used to describe the packet dropouts.A fault detection observer was designed to increase the fault sensitivity and attenuate the effects of disturbances.Based on linear matrix inequalities(LMIs) techniques,a sufficient condition was derived... |
