The secure consensus issue has been examined for multi-agent systems that are vulnerable to sequential scaling attacks with network communication delays in this paper. It is suggested to use the innovative sampled data based switching event-triggered techniques to prevent neighbors from constantly exchanging information. This research differs from previous works in that it introduces sequential scaling attacks, which combine deception and DoS attacks when communication delays are present. Then, the time-delay closed loop system is established by the technique of interval decomposition and the modeling method of augmented system. Moreover, based on the switching Lyapunov functional, a sufficient condition of the secure consensus is proposed by the utilization of linear matrix inequality technique with free weighting matrices. Finally, there are two illustrative examples employed to confirm the availability of the conceptual results.
