“…In recent decades, due to the development of cluster control such as unmanned aerial vehicle coordination, underwater cooperation, and robot formation control [1], consensus issues of multi-agent systems (MASs) have become the focus for many researchers. One of the fascinating topics is leader-following consensus [2], also known as model reference consensus [3], where a group of agents need to achieve consensus with the leader agents. It has been studied widely, for linear MASs [2] [4], nonlinear MASs [5], homogeneous or heterogeneous agents [6] under different scenarios.…”

This paper considers the leader-following consensus control for linear multi-agent systems. Two improved dynamic event-triggered control frameworks are proposed. The first one is based on a moving average approach, whereas the second is a fully-distributed control scheme based on a wellchosen Lyapunov function with rigorous proof of adjustable inter-event time. The proposed methods involve model-based estimation and clock-like auxiliary dynamic variables to increase the inter-event time as long as possible eventually. Compared to the static event-triggered strategy and the existing state-of-theart dynamic event-triggered mechanism, the proposed approach significantly reduces the communication frequency while still guaranteeing asymptotic convergence. Numerical simulations demonstrate the validity of the proposed theoretical results.

“…An extensive number of applications of UAVs have been proposed, such as agriculture assessment [13], search and rescue missions [14], marine exploration [15], and fire monitoring [16], among others [17]. Research works based on MASs using UAVs have considered the leader-following consensus related to Linear Time-Invariant (LTI) focused on second-order MASs with irregular discrete sampling times [18], particle swarm optimization [19], eventtriggered mechanisms [20], and communication faults [21]. Furthermore, [22] proposed an observer-based consensus control against actuator faults for Linear Parameter-Varying (LPV) MASs.…”

“…When the state error associated with the system does not meet this preset condition, the system will only perform a corresponding action, that is, controller update, as well as information transmission [21]. Event-triggered control can be divided into centralized event triggering and distributed event triggering [22]. In centralized event-triggered control, there is only one trigger condition in the system, and a control center is needed to obtain the state information of all the agents.…”

The time-sampling control strategy has communication discontinuities in the control of multiple AUVs (autonomous underwater vehicles). To overcome this problem, a distributed event-triggered communication mechanism is proposed to make each AUV communicate only when its own state is updated, which reduces the frequency of communication and improves the stability. This mechanism has better adaptability for formation control between heterogeneous AUV groups. At the same time, two consistency control algorithms based on event-triggered for homogeneous and heterogeneous AUV groups are studied, respectively. The known consistency algorithms are applied to the control of heterogeneous AUV groups for comparative analysis. The simulation results demonstrate that the number of communication among AUVs under the event-triggered control strategy can be significantly reduced. Therefore, the stability of the system is improved. Compared with the traditional consensus algorithm, the algorithm proposed in this paper has advantages in the control of heterogeneous AUV groups.
