In this paper, an optimal power allocation strategy for multiple denial-of-service attackers is investigated in a wireless networked control system with stochastic disturbances. In the presence of denial-of-service attackers, effective signals sent by a transmitter are interfered with causing degradation of signal-to-interference-plus-noise ratio and even packet loss. The effect of multiple attacks on the wireless networked control system is maximized by cooperative game. An H minimax controller is also designed to guarantee an optimal performance for the wireless networked control system in the worst case. A numerical example is conducted to verify the validity of the proposed methodology.
本文研究了具有随机干扰的无线网络控制系统中针对多个拒绝服务攻击者的最优功率分配策略。在存在拒绝服务攻击者的情况下，发射机发送的有效信号会受到干扰，导致信号与干扰加噪声比下降，甚至数据包丢失。通过合作博弈使多次攻击对无线网络控制系统的影响最大化。还设计了一个H极小极大控制器，以在最坏情况下保证无线网络控制系统的最优性能。通过一个数值例子验证了所提方法的有效性。
