摘要
本文研究一种新的分散信息平方根滤波算法。它不仅能由子滤波器的滤波计算结果合成得到总体意义上的系统状态最优滤波值,而且能由子滤波器的滤波计算结果直接合成得到主滤波器的状态估计误差的方差阵。
A new combining algorithm of decentralized square root information filtering for linear discrete-time systems is presented. In the approch not only the global state estimate, but also the error covariance of global estimate, can be combined by the local filtering results. The approch provides major improvements in throughput and is suited to real-time implementation.
