This paper investigates the problem of resilient decentralized control for nonlinear interconnected systems with unknown control directions under denial-of-service (DoS) attacks. For each subsystem, a novel switched sampled-data observer and an adaptive control architecture are respectively proposed to deal with the unavailable correction term in the existing results. Then a resilient decentralized adaptive controller is developed by employing the backstepping technique to reduce the negative influences of the system uncertainties and DoS attacks. By using average dwell time (ADT) and piecewise Lyapunov stability theories, one can ensure that the closed-loop system is semiglobally uniformly ultimately bounded (SUUB), while the output reference signal of each subsystem is tracked bounded. Furthermore, this scheme has a better utilization of computing and communication resources. Finally, the proposed scheme is verified by a power network system simulation.

本文研究了在拒绝服务 (DoS) 攻击下具有未知控制方向的非线性互连系统的弹性分散控制问题。对于每个子系统，分别提出了一种新颖的切换采样数据观测器和自适应控制架构，以处理现有结果中不可用的校正项。然后通过采用反步技术开发弹性分散自适应控制器，以减少系统不确定性和 DoS 攻击的负面影响。通过使用平均驻留时间（ADT）和分段李雅普诺夫稳定性理论，可以确保闭环系统是半全局一致最终有界（SUUB），同时每个子系统的输出参考信号被跟踪有界。此外，该方案更好地利用了计算和通信资源。最后，通过电网系统仿真验证了所提出的方案。
