Information Sharing Method in Federated Filter and Its Application in Transfer Alignment
Zhou Bai-ling · Journal of Nanjing University of Science and Technology · 2011
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.
