The dynamic event-triggered sliding mode control (SMC) method is used for the first time to address the consensus tracking problem of discrete-time multi-agent systems (MASs) in this brief. To avoid redundant data transmission, a dynamic event-triggered mechanism is introduced in the SMC. Considering the relationship between the leader and followers, a new sliding mode surface (SMS) related to the tracking error is designed. By designing a proper SMC law, sufficient conditions are obtained to ensure the accessibility of the specified SMS and consensus tracking. Finally, a group of comparative experiments are given to illustrate the validity of the proposed approach.
