This paper deals with the problem of environmental monitoring by developing an event-triggered finite-time control scheme for mobile sensor networks. The proposed control scheme can be executed by each sensor node independently and consists of two parts: one part is a finite-time consensus algorithm while the other part is an event-triggered rule. The consensus algorithm is employed to enable the positions and velocities of sensor nodes to quickly track the position and velocity of a virtual leader in finite time. The event-triggered rule is used to reduce the updating frequency of controllers in order to save the computational resources of sensor nodes. Some stability conditions are derived for mobile sensor networks with the proposed control scheme under both a fixed communication topology and a switching communication topology. Finally, simulation results illustrate the effectiveness of the proposed control scheme for the problem of environmental monitoring.
本文针对环境监测问题，开发了一种用于移动传感器网络的事件触发有限时间控制方案。所提出的控制方案可以由每个传感器节点独立执行，它由两部分组成：一部分是有限时间一致性算法，另一部分是事件触发规则。一致性算法用于使传感器节点的位置和速度在有限时间内快速跟踪虚拟领导者的位置和速度。事件触发规则用于减少控制器的更新频率，以节省传感器节点的计算资源。在所提出的控制方案下，针对固定通信拓扑和切换通信拓扑，分别推导了移动传感器网络的一些稳定性条件。最后，仿真结果说明了所提出的控制方案在环境监测问题中的有效性。
