| 摘 要： | 以组合导航系统为应用背景,在现有方法的基础上,提出Sage_ Husa自适应滤波算法的应用.采用常规卡尔曼滤波时,需要知道系统的数学模型和噪声统计的先验知识,但是在实际系统中,系统的数学模型和噪声统计是未知的、近似的或部分已知的.用不准确的模型或噪声统计设计出的卡尔曼滤波器将导致状态估值误差增大,甚至使滤波发散.Sag... |

| Abstract: | In view of the application of integrated navigation system,the paper presents a Sage_Husa adaptive filter algorithm based on the existing methods.The pre-knowledge of system mathematic model and noise statistic was required when using Kalman filter,but they were unknown,approximate or known partly in actual system.The estimated error value of system state was increased when an inaccurate model and statistic of noise were applied.The simulation results show that the Sage_Husa adaptive filter has high converg... |
