联邦滤波器信息分配原则的探讨

Discussion of Information Sharing Principe for Federated Filter

通过总结分析联邦滤波自适应改进中各种相互矛盾的信息分配原则,提出信息分配原则的三个核心问题,即信息分配系数对滤波精度、容错性的作用关系问题及滤波精度与容错性的相互关系问题。针对这三个问题,根据联邦滤波原理进行理论分析和证明,得出信息分配原则三个结论。仿真实验结果说明给出的三个结论成立,可以作为联邦滤波设计的理论依据。

By summarizing anti analyzing various contradictory information sharing principles in existing adaptive fed- erated filters, three core problems of information sharing principle, the effect of information sharing coefficient on filtering accuracy, the fault--tolerance and the relation between the filtering accuracy and the fault- tolerance, are raised . Three conclusions about the information sharing principle concerning above problems are obtained by theo- retical analysis based on basic principles of federated filter. Simulations are performed and the results show that the three given conclusions are valid and can be used as theoretical basis of federated filter design.
