7365 在SINS/GPS组合导航系统中,传统的无迹卡尔曼滤波(unscented Kalman filter,UKF)采用对称采样无迹变换(unscented transform,UT),计算量大,而且采样点到中心点的距离会随着状态维数的增加而增大,产生采样的非局部效应。 In the SINS/GPS integrated navigation system, no trace of the traditional Kalman filter (unscented Kalman filter, UKF) the symmetric sampling no trace transform (unscented transform, UT), large amount of calculation, and the sampling points to the center distance will increases, as the state dimension have a sampling of the nonlocal effect.
7366 针对以上问题,利用最小偏度单形采样策略降低UKF计算量以提高系统的实时性,采用比例UT变换来解决采样过程中的非局部效应,通过自适应调整比例因子来提高UKF的估计精度。 To solve above problems, the use of a minimum of skewness simplex sampling strategy to reduce UKF calculation in order to improve the real-time performance of the system, the proportion of UT transform is used to solve the nonlocal effects in the process of sampling, through the adaptive adjustment scale factor to improve the estimation precision of the UKF.
