我们研究了随机和恶意丢包对网络控制系统稳定性的影响。具体来说，我们探讨了网络控制问题，在这种情况下，设备和控制器交换状态并通过通信通道控制输入数据包，这可能面临随机传输失败以及智能代理的恶意攻击。我们得到了网络系统稳定的一个充分条件，并证明这个条件可以通过检验线性规划问题的解来评估。这些问题中的约束系数依赖于我们用来表征随机数据包丢失和恶意攻击的平均传输失败次数的渐近上界。我们用一个数值例子来说明我们的结果的有效性。
We investigate the effects of random and malicious packet losses on the stability of a networked control system. Specifically, we explore the networked control problem for the case where the plant and the controller exchange state and control input packets over a communication channel that may face random transmission failures as well as malicious attacks by an intelligent agent. We obtain a sufficient condition for the stability of the networked system and show that this condition can be assessed by examining the solutions to linear programming problems. The coefficients of the constraints in these problems depend on an asymptotic upper-bound for the average number of transmission failures that we use for characterizing random packet losses and malicious attacks. We illustrate the efficacy of our results with a numerical example.
