摘要
在总结旋转四元数方法和旋转矢量三子样优化算法的基础上,以高动态载体为对象,将2种航姿算法在Matlab环境下进行了仿真对比。仿真结果表明,在典型圆锥运动下,旋转四元数方法没有补偿不可交换误差,解算精度较低。旋转矢量优化算法在高动态载体的航姿解算中的姿态描述是有效和适用的。
The quaternion method and the optimal rotation vector three samples attitude algorithm are both summarized for high dynamic carriers in accordance with the motion characters of high dynamic carriers.Then two attitude algorithms are simulated and analyzed by the Matlab.A simulation for the accuracy of algorithms under the typical coning motion is presented.Results demonstrate that the operational precision of the quaternion method is less low because it does not compensate the noncommutativity error,and also...
