    研究短时延网络控制系统在具有数据包丢失情况下的故障检测问题.在丢包率一定的情况下,针对系统成功传输和丢包的情况分别设计故障观测器,将观测器误差方程建模为具有多个事件的异步动态系统,应用线性矩阵不等式方法推导出具有数据包丢失率约束的误差系统指数稳定的条件.仿真结果验证了该方法的有效性.

    The problem of fault detection for a class of Network Control System(NSC) with short time-delay and packet dropout is studied. Aimming at the case of successful transmission and lost, the fault observer is designed respectively. Based on the fixed rate of the data packet dropout, the error equation of the observer is modeled as an asynchronous dynamic system with multi-events. The stability condition of error system with rate constraints on data packet dropout is given in terms of a group of Linear Matrix Inequalities(LMI). Simulation result verifies the effectiveness of the proposed method.
