This paper considers a reliable cooperative control and plug-and-play operation problem in networked heterogeneous systems (NHSs), and focuses on the scenario subjected to physical attack-induced actuator failures/uncertainties and Denial-of-Service (DoS) attacks on communication channels between physical nodes. To solve it, a new self-feedback control with an adaptive integral sliding-mode compensator is developed. The new one configures each heterogeneous system under the malicious actuator failures/uncertainties to be passivity-short (PS). The PS index quantifies the impact of each attacked heterogeneous dynamics on their networked operations. Furthermore, based on cloud networks, a novel network-level distributed control is proposed. It improves robustness of the systems against DoS with no frequency and duration constraints. And then, a technical condition is presented with the aid of the impact equivalence principle. Under the condition, the self-feedback and network-level controls designed separately but performed together ensure the leader-follower consensus and plug-and-play operation of the attacked NHSs. Finally, the effectiveness of the proposed method is verified by flight control systems.
本文考虑了网络化异构系统（NHSs）中的可靠协同控制和即插即用操作问题，并聚焦于遭受物理攻击导致的执行器故障/不确定性以及物理节点之间通信信道上的拒绝服务（DoS）攻击的场景。为解决该问题，开发了一种带有自适应积分滑模补偿器的新型自反馈控制。这种新控制将受恶意执行器故障/不确定性影响的每个异构系统配置为被动短（PS）系统。PS指标量化了每个受攻击的异构动态对其网络化操作的影响。此外，基于云网络，提出了一种新颖的网络级分布式控制。它提高了系统对DoS攻击的鲁棒性，且无频率和持续时间限制。然后，借助影响等效原理给出了一个技术条件。在该条件下，分别设计但共同执行的自反馈和网络级控制确保了受攻击的NHSs的主从一致性和即插即用操作。最后，通过飞行控制系统验证了所提方法的有效性。
