摘　　要：研究了同时具有大于一个采样周期的随机传输时延及数据包丢失的网络控制系统的稳定性问题.对于给定的数据包丢失率,网络控制系统被建模为具有两个事件速率约束的异步动态系统,利用异步动态系统理论给出了网络控制系统指数稳定的充分条件,状态反馈控制器可通过解一组矩阵不等式求出.仿真示例验证了所提出方法的有效性.The stability of networked control systems, with stochastic transmission delay larger than one sampling period and the dropped out packets, is studied. For the given data packet dropout, the networked control systems is modeled as an asynchronous dynamical system with rate constraints on two events. The sufficient condition of exponential stability for the networked control systems is presented based on the theory of asynchronous dynamical system. Meanwhile the state feedback controller can be solved by a set of matrix inequalities. A numerical example shows the effectiveness of the proposed method.
