本文讨论了拒绝服务（DoS）攻击下的量化输出反馈稳定。首先，假设DoS攻击的持续时间和频率是平均有界的，并且植物状态的初始界是已知的，我们提出了一种输出编码方案，该方案在有限的数据速率下实现指数收敛。接下来，我们表明，一个合适的状态转换允许我们删除的假设上的拒绝服务频率。最后，我们讨论了在拒绝服务攻击下的状态界的推导，得到了闭环系统达到Lyapunov稳定的拒绝服务持续时间和频率界的充分条件。
This article addresses quantized output feedback stabilization under denial-of-service (DoS) attacks. First, assuming that the duration and frequency of DoS attacks are averagely bounded and that an initial bound of the plant state is known, we propose an output encoding scheme that achieves exponential convergence with finite data rates. Next, we show that a suitable state transformation allows us to remove the assumption on the DoS frequency. Finally, we discuss the derivation of state bounds under DoS attacks and obtain sufficient conditions on the bounds of DoS duration and frequency for achieving Lyapunov stability of the closed-loop system.
