An Improved Protocol to Consensus of Delayed MASs With UNMS and Aperiodic DoS Cyber-Attacks

The present research focuses on the issue of leader-following consensus for multi-agent systems (MASs) suffered from uncertain nonhomogeneous Markov switching (UNMS), time-varying delay, and denial service (DoS) cyber-attacks. Firstly, in contrast with existing results MASs, communication topology is governed by a UNMS jump process which transition rates (TRs) may be partially known or completely unknown. Secondly, changes topologies due to frequently aperiodic DoS cyber attacks are taken into consideration, destroy chains lead network paralysis MASs. By introducing concepts average ratio, novel mean-square conditions establish relationship between control gains sleeping, active periods signal MASs proposed. It shows that there no direct restriction delay system intervals sleeping period jamming signal. Finally, theoretical result validated numerical example.
