本文提出了一种分布式观测器来估计线性时不变对象在有限时间内每个观测器节点的状态。该设计基于分解为局部可观测和不可观测的子态以及齐次系统的性质。每个观测器节点可以在有限时间内仅利用其测量值重构其局部可观测子状态。然后利用这种耦合，通过加入一致项，构造了剩余状态的有限时间收敛观测器。数值算例说明了结果。
In this paper, a distributed observer is presented to estimate the state of a linear time-invariant plant in finite-time in each observer node. The design is based on a decomposition into locally observable and unobservable substates and on properties of homogeneous systems. Each observer node can reconstruct in finite-time its locally observable substate with its measurements only. Then exploiting the coupling, a finite-time converging observer is constructed for the remaining states by adding the consensus terms. A numerical example illustrates the result.
