摘要： 对一类具有时延及数据包丢失的正则、无脉冲广义网络控制系统进行分析,其中传感器采用时钟驱动,控制器和执行器采用事件驱动.假设传输时延小于一个采样周期,数据包传输成功率一定,将广义网络控制系统进行建模为异步动态系统,同时利用李雅普诺夫函数和线性矩阵不等式方法,给出系统稳定的充分条件.借助于Matlab LMI工具箱,可在判定系统稳定的同时,获得使系统稳定的状态反馈控制律.最后的仿真实例表明该方法的可行性.

Abstract: The regular and impulsive-free singular NCSs (networked control systems) with networked-induced delay and data packet dropout are discussed, where the sensor node is time-driven but the controller and executor are event-driven. Assuming that the transfer delay is shorter than the sampling period and the data packets can be transferred successfully at a constant rate, the singular NCS can be modeled as an asynchronous dynamical system. With the Lyapunov function and LMI (linear matrix inequality) method, the sufficient conditions for stability is given and, by virtue of the Matlab LMI toolbox, the desired state feedback control law is given at the same time. A simulation example is given to illustrate that the proposed method is efficient.
