Abstract
In this letter, a distributed periodic event-triggered (PET) consensus protocol is proposed for nonlinear multiagent systems under directed communication topology switchings. Only at the sampling instants, the information exchanges and the modes of topologies are used. Then, a distributed PET controller with a discrete event-triggering mechanism is proposed to reduce the burden of communication. By deriving a novel average dwell time constraint and constructing multiple Lyapunov functions, the leader–following consensus objective can be achieved. Finally, the proposed method's effectiveness is demonstrated by simulation results.
本文针对定向通信拓扑切换下的非线性多代理系统提出了一种分布式周期事件触发（PET）共识协议。该协议仅在采样时刻使用信息交换和拓扑模式。然后，提出了一种具有离散事件触发机制的分布式 PET 控制器，以减轻通信负担。通过推导新的平均停留时间约束条件和构建多个 Lyapunov 函数，可以实现领导-跟随共识目标。最后，模拟结果证明了所提方法的有效性。
期刊介绍：
This publication provides a systems-level, focused forum for application-oriented manuscripts that address complex systems and system-of-systems of national and global significance. It intends to encourage and facilitate cooperation and interaction among IEEE Societies with systems-level and systems engineering interest, and to attract non-IEEE contributors and readers from around the globe. Our IEEE Systems Council job is to address issues in new ways that are not solvable in the domains of the existing IEEE or other societies or global organizations. These problems do not fit within traditional hierarchical boundaries. For example, disaster response such as that triggered by Hurricane Katrina, tsunamis, or current volcanic eruptions is not solvable by pure engineering solutions. We need to think about changing and enlarging the paradigm to include systems issues.
