[Abstract]:With the consistency of multi-agent systems widely used in sensor networks, formation control, UAV, mobile robot coordination control and other fields, it has become a research hotspot in the field of control. In many practical systems, the limitation of communication network bandwidth and resources affects the realization of system consistency. In this paper, the event triggering strategy is introduced to ensure the consistency of the system while reducing the consumption of communication resources and computing resources. The main contents of this paper are as follows: (1) the consistency of multi-agent under adaptive event trigger control scheme is analyzed. The proposed control scheme can dynamically adjust the trigger time interval according to the sampled data, improve the control performance of the system and save communication resources. By using Lyapunov stability theory, the conditions of consistency are given by using linear matrix inequalities. (2) two multi-agent networks with the same topology are considered, one of which is the leadership, the other is the following layer. A new event-triggered traction control scheme is proposed to achieve the consistency between the two networks. Only part of the follower can communicate directly with the corresponding leader and update the traction controller if the event trigger condition is violated. Secondly, the corresponding theoretical results are extended to nonlinear systems. Furthermore, the H 鈭，
