Abstract:
This paper investigates the prescribed-time resilient containment control (PTRCC) problem for leader-following multi-agent systems (MASs) subject to denial of service (DoS) attacks and disturbances. To alleviate communication burdens, a novel resilient dynamic event-triggered mechanism (RDETM) is developed for the controllers, which adaptively adjusts its threshold based on the attack status to reduce redundant transmissions during DoS attack intervals while excluding Zeno behavior. Simultaneously, disturbance observers are integrated into the control scheme to actively compensate for external disturbances. Subsequently, a prescribed-time resilient containment controller is developed for each follower. Theoretical analysis confirms that the proposed control strategy achieves the containment control objective within a user-defined prescribed time. Finally, simulation-based validation is provided to demonstrate the effectiveness of the proposed approach.
