Owing to the development of networking, most systems operate in a wireless network environment.However, due to the unreliability of network communication, it is difficult to ensure the security of data transmission. Common network attacks, such as DoS attacks, will disrupt the regular operation of the system, which will bring greater challenges to the design of the controller. In this work, we try to develop an intelligent security control strategy for multi-agent systems under the network environment with DoS attacks. Based on the event-triggered strategy, a novel dual-event-triggered mechanism is developed to eliminate the impact of DoS attacks on the system. A two-layer nested event-triggered mechanism prevents the system from receiving incorrect control signals due to DoS attacks. Finally, the results are applied to the intelligent mobile robot system, showing its resistance to DoS attacks, indicating that it can be further extended to practical applications.

The intelligence security control problem of multiagent systems in the presence of actuator faults is investigated against denial-of-service (DoS) attacks. Noticing that the DoS attacks usually make the actuator signal not available for distributed control protocols, a novel intelligence dual-event-triggered control strategy is developed to eliminate the impact of DoS attacks. This control strategy includes two related event triggers, respectively, set on different channels, in which the second event-triggered condition is related to the triggering sequence of the previous event. Through the coordination between two nested event triggers set on different channels, the controller is avoided by being affected by wrong signals caused by DoS attacks. The developed distributed control protocol can not only guarantee the realization of the tracking control task, but also ensure that no “Zeno behavior” occurs in the process of the event triggering. Moreover, the obtained results are applied t...
