研究了有向通信拓扑下具有时变参考速度的多车辆系统的两种不同的一致性策略,其中系统采用双积分动力学模型.对于固定通信拓扑的情况下,我们提供了一个必要和充分条件的参考速度的所有车辆达成共识,通过使用一种新的图形方法。然后,我们扩展这种方法来处理一般情况下,即,通信拓扑结构和权重因子都是动态变化的。特别是,它表明,所有的车辆可以达成共识,即使动态变化的交互拓扑可能没有一个全球可达的节点。
This paper investigates two kinds of different consensus strategies for multi-vehicle systems with a time-varying reference velocity under directed communication topology, where the systems are modeled by double-integrator dynamics. For the fixed communication topology case, we provide a necessary and sufficient condition for all the vehicles with reference velocity to reach consensus by the use of a new graphic methodology. We then extend this method to deal with the general case, that is, both the communication topologies and weighting factors are dynamically changing. In particular, it is shown that all the vehicles can reach consensus even though the dynamically changing interaction topology may not have a globally reachable node.
