This paper is concerned with the discrete event-triggered dynamic output-feedback |${H}_{\infty }$| control problem for the uncertain networked control system, where the time-varying sampling, network-induced delay and packet losses are taken into account simultaneously. The random packet losses are described via the Bernoulli distribution. And then, the closed-loop system is modelled as an augmented time-delay system with interval time-varying delay. By using the Lyapunov stability theory and the augmented state space method, the sufficient conditions for the asymptotic stability of the closed-loop system are proposed in the form of linear matrix inequalities. At the same time, the design method of the |${H}_{\infty }$| controller is created. Finally, a numerical example is employed to illustrate the effectiveness of the proposed method.

NCS的事件触发Hꝏ控制，具有时延和数据包丢失

本文涉及离散事件触发的动态输出反馈| $ {H} _ {\ infty} $ | 不确定网络控制系统的控制问题，同时考虑时变采样，网络引起的延迟和数据包丢失。随机分组丢失通过伯努利分布来描述。然后，将闭环系统建模为具有间隔时变延迟的增强时延系统。利用李雅普诺夫稳定性理论和扩充状态空间方法，以线性矩阵不等式的形式提出了闭环系统渐近稳定性的充分条件。同时，| $ {H} _ {\ infty} $ |的设计方法控制器已创建。最后，通过算例说明了该方法的有效性。
