Dynamic event-Based resilient consensus of networked lagrangian systems under DoS attacks

In this paper, the dynamic event-based resilient consensus control of the multiple networked Euler-Lagrangian (E-L) systems under the Denial of Service (DoS) attacks is considered. Compared with linear cyber-physical systems, nonlinear networked E-L systems are more complex and closer to actual mechanical systems. For the situation where the topology is a strongly connected directed topology, a controller based on a dynamic event-trigger mechanism is designed to achieve consensus control for the networked E-L system in the absence of DoS attacks. Sufficient conditions are presented, which can guarantee the closed-loop system be stable. Then the resilient consensus problem of event-based controllers under energy-constrained DoS attacks is analyzed. The conditions related to the duration and frequency of DoS attacks are given. Zeno behavior is proved does not exist in the proposed control scheme. Finally, some numerical simulation results are given for verifying the theoretical results. & COPY; 2022 The Franklin Institute.

Automated summary

This paper focuses on the dynamic event-based resilient consensus control of multiple networked Euler-Lagrangian systems under Denial of Service (DoS) attacks. Nonlinear networked Euler-Lagrangian systems are more complex and closer to actual mechanical systems compared to linear cyber-physical systems. A controller based on a dynamic event-trigger mechanism is designed to achieve consensus control for the networked E-L system when there are no DoS attacks. Sufficient conditions for stability of the closed-loop system are presented, and the resilient consensus problem under energy-constrained DoS attacks is analyzed.
