摘　　要：针对一类同时具有时延和丢包的正则无脉冲且脉冲能观的广义网络控制系统,假设传输时延小于一个采样周期且网络中的数据包传输成功率一定,将该系统建模为异步动态系统.利用李雅普诺夫函数和线性矩阵不等式方法给出判断系统指数稳定的条件,并且得出基于正常状态观测器的反馈控制器.仿真实例证明了该方法的有效性.Assuming that the transfer delay is shorter than the sampling period and the successful rate of data packet transfer is given,the singular networked control system could be modeled as an asynchronous dynamical system for a class of the regular,impulsive-free and impulsive observable singular networked control systems with delay and data packet dropout.The stability conditions of the system were given with the Lyapunov function and LMI method,and the feedback controller with the normal state observer was obtained.Simulation results indicated the effectiveness of the proposed method.
