In this paper, the input-to-state stability (ISS) control problem is studied for cyber-physical systems (CPSs) in the presence of asynchronous denial-of-service (DoS) attacks. To enhance the exponential ISS, an intelligent packet-based control method with buffering is proposed by introducing the acknowledgement signal (ACK), in which the trial transmission attempts of the control packet are intelligently determined by the situation (successful or failed) of its last sampling transmission instant after identifying the unnecessary transmission points and the necessary transmission points. Then, inspired by the packet-based control technology with buffering, the sufficient condition for attempting transmission of the control packet is given, in which the exponential ISS with maximum robustness index can be preserved. Compared with the existing method with a fixed transmission rate for the control packet, it is shown that the considered framework improves the exponential ISS performance with equal or less communication resource costs.

在本文中，研究了存在异步拒绝服务 (DoS) 攻击的网络物理系统 (CPS) 的输入到状态稳定性 (ISS) 控制问题。为了增强指数ISS，提出了一种基于分组的智能缓冲控制方法，通过引入确认信号（ACK），其中控制分组的试传尝试由其最后的情况（成功或失败）智能决定。在识别出不必要的传输点和必要的传输点后采样传输瞬间。然后，受带缓冲的基于包的控制技术的启发，给出了尝试传输控制包的充分条件，其中可以保留具有最大鲁棒性指标的指数ISS。
