本文讨论了有向图上高阶积分多智能体系统的分布式一致性观测器设计问题,该问题旨在于给定的时间间隔内精确估计领导状态。首先,提出了一种新的有向图上的分布式规定时间观测器(DPTO),并以级联方式实现。然后,基于严格的李雅普诺夫稳定性分析和数学归纳法,保证了上述DPTO对于时不变和时变有向相互作用拓扑的规定时间零误差估计性能。最后,通过数值仿真实例说明了这种新的分布式观测器的实用性和有效性。
This brief deals with the distributed consensus observer design problem for high-order integrator multi-agent systems on directed graphs, which intends to estimate the leader states accurately in a prescribed time interval. A new kind of distributed prescribed-time observers (DPTO) on directed graphs is first formulated for the followers, which is implemented in a cascading manner. Then, the prescribed-time zero-error estimation performance of the above DPTO is guaranteed for both time-invariant and time-varying directed interaction topologies, based on strictly Lyapunov stability analysis and mathematical induction method. Finally, the practicability and validity of this new distributed observer are illustrated via a numerical simulation example.
