研究了随机混合系统在能量受限的拒绝服务攻击下的稳定性问题，引入基于采样数据的循环调度协议避免网络拥塞，并通过分段李雅普诺夫-克拉索夫斯基函数和随机分析技术分析系统稳定性。
The stability issue of stochastic hybrid systems against energy-constrained denial-of-service (DoS) attacks is investigated in this article. A sampled-data-based Round-Robin protocol, which sends measurement data cyclically according to the predetermined transmission sequence, is introduced to avoid communication network congestion. Additionally, a new switched time-delay stochastic closed-loop system with an unstable subsystem is established by discussing the effect of DoS attacks. Then, the stability of the closed-loop system is discussed in light of the piecewise Lyapunov–Krasovskii functional method and stochastic analysis technique. Finally, two examples are included to illustrate the correctness and applicability of the proposed method.
