| 摘 要： | 针对寻北陀螺仪允许测漂时间短、工作于车载动态环境的特点，本文对应用平均选点算法回归计算寻北陀螺仪漂移角速度进行了研究，并与最小二乘算法进行了比较。结果表明，平均选点算法简单，运算量小，回归结果受测试数据波动变化的影响小，采样接口电路简单易于工程实现，且无需对测漂回路多次采样，消除了采样噪声的影响，是回归计算寻北陀螺仪漂移角速度的一种合适算法。

| Abstract: | Considering north seeking gyroscope's limit of short drift test time and it works in vehicle dynamic condition , this paper introduces mean - pick - point al- gtorithm for regressing north - seeking gyroscope's angle drift rate. The calculation is quite simple and short and the sample circuit is easy to realize in engineering. There is no need to sample d rift test circuit frequently and the interference of sample noise is e- liminated. Compared with least square algorithm , the regressed parameters of mean - pick - point algorithm are less influenced by test data variation. Mean - pick - point al- gorithm is more suitable for regression of north - seeking gyroscope's angle drift rate. |
