摘要/Abstract

摘要： 针对分布式状态估计中卡尔曼一致滤波算法各节点间通信量过大的问题，在保证卡尔曼一致滤波算法估计精度及各节点估计值一致性前提下，为减少各节点间的通信量，提出一种事件触发机制协调各节点间的信息交互过程。推导了相应的卡尔曼一致滤波算法，并证明了其估计误差的有界性；仿真了所提算法在不完全量测下光电探测网中的应用。研究结果表明：与经典卡尔曼一致滤波算法相比，所提算法可在节约网络通信资源前提下，保证网络中各节点估计精度及估计值的一致性。

Abstract: This paper focuses on the problem of the too much communication amount of the Kalman consensus filtering (KCF) algorithm in the distributed state estimation. An event-triggered mechanism is proposed to decrease the communication amount among nodes, meanwhile ensuring the estimation accuracy and the consensus of estimated values of each node. The corresponding estimation algorithm is derived. The boundedness of estimated error of the proposed algorithm is also proven. The proposed algorithm is tested in an electro-optical sensor network with intermittent measurements. The result shows that, compared with the classical Kalman consensus filtering algorithm, the proposed algorithm can save the network’s communication resources and ensure the estimation accuracy of each node in the network.
