摘　　要：首先证明了联邦滤波器中各局部滤波器实际上滤波不相关,然后通过使用集中式滤波器的滤波稳定性定理,来分析联邦滤波器的滤波稳定性。仿真实验首先根据上述方法证明了联邦滤波器的滤波稳定性,然后通过改变滤波初始值的方法对上述方法的执行结果进行了实验验证。This paper first demonstrates that all of the local filters of federated filter are in fact uncorrelated with each other. Then, a method is obtained to judge the stability of federated filter by using the stability theorem of filter. Simulation proves the stability of federated filter designed in this paper and the practical experiment testified the proposed method by altering initial value.
