针对无线网络控制系统动态特性面临外生干扰的情况，研究了干扰攻击对系统的影响。特别地，控制输入分组被假设为通过易受干扰攻击的不安全无线通信信道从控制器传输到远程定位的线性设备。该信道上传输失败的时变可能性取决于攻击者发出的干扰信号的功率。我们表明，干扰攻击可以防止稳定的系统面临干扰时，即使没有干扰的攻击系统是稳定的。我们还表明，在干扰和扰动下的稳定性，可以实现如果平均干扰干扰功率以一定的方式，我们在这篇文章中描述的限制。我们说明了我们的研究结果的一个例子网络控制系统与衰落的无线信道，中断概率受到干扰攻击。
Jamming attacks on wireless networked control systems are investigated for the scenarios where the system dynamics face exogenous disturbance. In particular, the control input packets are assumed to be transmitted from a controller to a remotely located linear plant over an insecure wireless communication channel that is subject to jamming attacks. The time-varying likelihood of transmission failures on this channel depends on the power of the jamming interference signal emitted by an attacker. We show that jamming attacks can prevent stability when the system faces disturbance, even if the attacked system without disturbance is stable. We also show that stability under jamming and disturbance can be achieved if the average jamming interference power is restricted in a certain way that we characterize in this article. We illustrate our results on an example networked control system with a fading wireless channel, where the outage probability is affected by jamming attacks.
