| 摘 要： | 在常规弹箭上应用固态微惯系统具有重要意义.该文研究各种航姿算法对常规弹箭高动态运动特征的适应性.以高动态规则进动作为运动输入,仿真四元数航姿算法和旋转矢量多子样算法的漂移.误差分析和数值仿真结果表明:高动态环境下,引入了角速率项的旋转矢量修正二子样算法能较好地适应由新型固态陀螺构建的捷联系统.

| Abstract: | It's important to apply MIMU to conventional rocket.The applicability of kinds of attitude algorithms's to highly dynamic character of rocket are discussed in this paper.A regular precession signal as the theoretical value to evaluate the drifts of quaternation and rotation vector attitude algorithms.Both theory derivation and simulation indicates that modificatory two-samples algorithm is relatively effective when highly dynamic regular precession angular rate signal is given. |
