摘要
分析了在系统无故障和故障两种情况下,信息分配系数对各子滤波器的影响;研究了当前的几种典型动态信息分配方法在改变系统的全局融合估计和故障容错性能方面的局限性;基于提高无故障子系统的容错性考虑,提出了一种具有容错性的信息分配思想,可以改善重构后联邦滤波器的快速恢复能力。仿真结果证明了本文方法的有效性。
With a detailed analysis of the information sharing factors＇ influence on the local filters in two states, good and faulty, this paper discusses the disadvantages of the several adaptive information sharing schemes given in the present case. To improve the ability of recovery of the federated filter by heightening the healthy local filters＇ resistance to the contamination from the faulty local liters, a fault-tolerant information sharing idea is provided. Simulation shows this scheme is effective.
