摘要:
针对高动态导航环境中固定信息分配策略不能满足应用需求的问题,根据联邦滤波公式定量分析了信息分配系数的选择对各子滤波器精度、鲁棒性及计算稳定性的影响。考虑通过提高无故障子滤波器的鲁棒性来提高联邦滤波器的快速重构能力,同时兼顾子滤波器的精度和计算稳定性,提出了基于模糊规则表的信息分配策略,给出了实现该策略的具体方法,并将其用于某导航系统的快速传递对准中。理论分析与仿真结果表明,该方法可以有效提高无故障子系统对系统故障的抗干扰能力,并可保证系统的计算稳定性。
Abstract:
Given the fixed information-sharing method can not satisfy the application requirement in high dynamic navigation circumstance,the influence of information sharing coefficients selection on the accuracy,robustness and stability of local filters is investigated quantitily using the federated filter algorithm.To improve the reconfiguration ability of federated filter by improving the robustness of local filters,and to improve the accuracy and calculation stability of local filters,the information sharing scheme based on fussy rule table is presented,and the specific manipulation method is given.The method proposed in this paper is applied in the rapid transfer alignment of a guidance system.Theoretical analysis and simulation results show that this method can improve the anti-disturbance ability of sub-system and also guarantee the calculation stability.
