研究二阶连续多智能体系统的一致性问题,其中每个智能体只能在一系列离散时刻上获得位置信息.为了关于完全状态,即位置和速度,都达到一致,设计一类协议,并建立在该协议下,一致性成立的充要条件.该条件揭示了交流拓扑、控制器增益、采样周期和保持器的更新周期之间的关系.仿真例子表明理论结果是有效的.
This paper is concerned with consensus problems of continuous-time second-order agents, where each agent can only obtain position information relative to its neighbors at some sampling instants. A protocol is designed for reaching consensus on full state, i.e., position and velocity, and a sufficient and necessary condition for consensus is obtained. The sufficient and necessary condition shows the clear relationship among the interaction topology, controller gains, and the periods of sampler and zero-order hold. Simulations are performed to validate the theoretical results.
