The problem of consesus control of nonlinear Multiagent Systems (MAS) in environments undergoing denial-of-service (DoS) attacks is investigated. Firstly, to prevent the impact of DoS attacks on the consensus of the MASs, a distributed switch state observer is introduced to estimate the states of the leader and detect the occurrence of DoS attacks. Secondly, a first-order filter is employed to reduce computational complexity. Next, by utilizing the observer states and filtering accessible states, we employ the backstepping technique to develop a distributed controller for every follower agent to achieve consensus among all agents. Lastly, we validate the efficiency of the proposed control strategy by presenting simulation outcomes.

Secondly, a first-order filter is employed to reduce computational complexity. Next, by utilizing the observer states and filtering accessible states, we employ the backstepping technique to develop a distributed controller for every follower agent to achieve consensus among all agents. Lastly, we validate the efficiency of the proposed control strategy by presenting simulation outcomes.
