| 摘 要： | 研究一类具有时延和数据包丢失的网络控制系统故障检测问题.当数据包丢失率一定时,针对系统是否存在数据包丢失的两种情况,分别设计了状态观测器,并将整个观测器系统等效为具有两个事件的异步动态系统,给出了系统指数稳定的矩阵不等式条件和故障检测的判断规则.最后通过仿真示例验证了所提出方法的有效性.

| Abstract: | The problem of fault detection is studied for a class of networked control systems with time delays and data packet dropout.When data packet rate is fixed,the state observer is designed respectively for the system with or without data packet dropout.And the whole observer system is equal to the asynchronous dynamical system with two events.The matrix inequality conditions for the exponential stability and the decision rule for fault detection of the system are given.Finally,an illustrative example shows the... |
