Abstract

The security control is studied for discrete nonhomogeneous semi-Markov switching power systems under network attacks. In view of time-varying transition probability, a nonhomogeneous semi-Markov chain is introduced to accurately model transient faults of power lines and dynamic switching of circuit breakers. Due to the random nature of denial-of-service (DoS) attacks, Bernoulli process is adopted to characterize the attacks behavior. Based on the semi-Markov kernel and Lyapunov function depending on the current system mode and dwell time, sufficient conditions for the existence of the controller are derived to ensure the mean-square stability of the closed-loop system. Finally, the effectiveness and practicability of the proposed control strategy are verified by a numerical case.

具有DoS攻击的网络非齐次随机开关电源系统安全控制

研究了离散非齐次半马尔可夫开关电源系统在网络攻击下的安全控制问题。针对时变过渡概率，引入非齐次半马尔可夫链，对电力线路暂态故障和断路器动态切换进行精确建模。由于DoS （denial-of-service）攻击的随机性，采用伯努利过程对攻击行为进行表征。基于半马尔可夫核和依赖于当前系统模式和停留时间的李雅普诺夫函数，导出了保证闭环系统均方稳定的控制器存在的充分条件。最后，通过数值算例验证了所提控制策略的有效性和实用性。
