本文研究了一般有向图下连续时间线性多智能体系统的分散周期事件触发一致性问题。基于零阶保持对连续时间MAS进行离散化处理,提出了一种事件触发的一致性控制(ETCC)算法,使Agent的状态达到一致。他们证明,在多个步骤中实现的建议ETCC下,在采样的意义上没有表现出类似Zeno的行为。为了放宽ETCC中周期性监控的要求,进一步提出了自触发共识控制算法,其中下一个触发时刻由每个代理在前一个触发时刻预先确定。对于MAS状态不可用的情况,作者进一步提出了一种基于时间序列的ETCC算法。仿真结果验证了理论分析的正确性。
This study considers the decentralised periodic event-triggered consensus problem for continuous-time linear multi-agent systems (MASs) under general directed graphs. The authors discretise the continuous-time MASs based on zero-order hold, and propose an event-triggered consensus control (ETCC) algorithm rendering the states of agents reach consensus. They prove that under the proposed ETCC implemented in multiple steps, there is no Zeno-like behaviour exhibited in the sense of sampling. To relax the requirement of the periodic monitoring in the ETCC, it is further proposed a self-triggered consensus control algorithm, where the next triggering instant is predetermined by each agent at the previous triggering instant. For the case where the states of MASs are unavailable, the authors further propose an observer-based ETCC algorithm. Simulation results are given to illustrate the theoretical results.
