Chengkai Tang · Jisuanji fangzhen · 2009
Through introducing the basic principle and the algorithm of Federated Kalman Filter,this paper discusses the function of the information sharing factor in Federated Kalman Filter.According to different information sharing factors' influence on Federated Kalman Filter's state estimate precision,and by calculating the algorithm of Federated Kalman Filter,the paper proves theoretically that different information sharing factors can't change filter's state estimate precision,they can only improve subsystem's state estimate precision.The result of the simulation indicates that different information sharing factors only have effects on subsystem's state estimate precision.
