Sliding Mode Interval Observer-Based Controller Design for Multi-Agent Systems Under DoS Attack
Xinhai Shen, Jinfeng Gao, Peter Xiaoping Liu · IEEE Systems Journal · 2023
The consensus problem of the multi-agent systems with uncertainty and denial-of-service attack is studied. The interval observer control method is utilized to reduced the influence of unknown external disturbances. By introducing sliding mode term, the observation error of the system is released and the robustness is improved. Using the coordination theory, the control algorithm based on the sliding mode interval observer drive the uncertain system to achieve the coordinated consensus. In order to make the multi-agent systems achieve asymptotically consensus under denial-of-service attack, an attack time security protocol based on persistent dwell time scheme is proposed. Finally, the simulation results are given to demonstrate the validity and superiority of the proposed method.
