Multiagent systems are often applied in unmanned aerial vehicle formations, multi-manipulator coordinated, traffic vehicle control and other fields, which have attracted a lot of attention from scholars. In this paper, considering the given transient performance of multiagent systems, its synchronization error converges to the predefined interval by designing the performance function. In the meanwhile, through the designed nonlinear transformation of synchronization error, a prescribed setting time tracking control is realized, which can ensure that the multiagent systems are uniformly bounded convergent. In addition, event-triggered strategy is introduced to economize the utilization of multiagent systems' communication resources. Finally, theoretical analysis and simulation research demonstrates the effectiveness of the proposed method.
