Both theory derivation and simulation indicates that modificatory two-samples algorithm is relatively effective when highly dynamic regular precession angular rate signal is given. 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。
Some characteristics of regular precession vector 规则进动矢量的若干性质
This article extends the concept of regular precession of angular momentum vector to any mathematical and physical vector. 本文将力学中角动量矢量的规则进动的概念拓展到任意数学或物理矢量之上;
There exist three possible stationary motions of the sphere. The permanent rotations about its symmetric axis with the center of mass, lower or higher the center of sphere, and the regular precession with a definite nutation angle. 分析表明,刚球存在三种可能的稳态运动,即质心低于或高于球心绕对称轴作永久转动,或以某个确定章动角作规则进动。
Test inputs for attitude algorithm of SINS and the evaluating criterion of each attitude algorithm are summarized, such as in pure coning motion, generalized coning motion, regular precession, stochastic angular motion, and benign environment. 总结了经典圆锥运动、广义圆锥运动、规则进动运动、随机角运动、温和环境等捷联姿态算法的测试输入及各自评价姿态算法性能的标准。
