Abstract
- This article investigates the practical fixed-time consensus for nonlinear multi-agent systems (MASs) in the presence of denial-of-service (DoS) attack utilizing aperiodically intermittent event-triggered control protocol. Unlike predefining the distribution of DoS attack intervals, an attack detection algorithm is designed to identify the onset and cessation of attack intervals in a dynamic manner. Subsequently, by incorporating the aperiodically intermittent control scheme with the event-triggered mechanism, an efficient control protocol is designed that guarantees the fixed-time consensus for nonlinear MASs under DoS attacks and exhibits resilience against certain attack sequences. Furthermore, in order to address the Zeno and non-differentiable issues, the hyperbolic tangent function is employed in the design of nonlinear controller. Moreover, the control protocol utilizing a non-continuous monitoring event-triggered mechanism is also developed to save more communication resources. Finally, simulations are performed to verify the efficacy of the proposed control protocol. [ABSTRACT FROM AUTHOR]
