Dual-Channel Event-Triggered Scaled Consensus for Multiagent Systems on Time Scales Under DoS Attacks.

This article focuses on the scaled consensus problem of time-scale-type multiagent systems (MASs) under communication networks subject to denial-of-service (DoS) attacks. A dual-channel dynamic event-triggered mechanism (DETM) is proposed to reduce both actuator update frequency and communication overhead. By constructing a nonnegative function integrated with time-scale calculus theory, sufficient conditions are derived to guarantee the scaled consensus while excluding Zeno behavior. The conclusions derived from this method can be applied to MAS models in both continuous and discrete time domains. Finally, a numerical simulation and a case study on autonomous marine vehicles (AMVs) are presented to validate the effectiveness and feasibility of the proposed approach.
