Using the principle of limited rigid body rotation and the characteristic of angular rate input  three-sample rotation vector algorithm is derivated. To minimum attitude errors  three-sample rotation vector algorithm is optimized. Three angular rate extraction methods of singlestep entire sample recursion  multi-step entire sample and singlestep Newton backward interpolation are proposed. Under the condition of conical motion with semi-cone angle 3 and angular frequency 2rad/s  simulation is done. The simulation results show that single-step Newton backward interpolation is superior to the other two methods  and its maximum error peak is 0.01  error drift rate is 0.036/h. Experiments in three-axis flying turntable with the same parameters are carried out  and the results show that error drift rates of three-channels are less than those of traditional quaternion  which are 13.53%  12.08% and 23.68% lower respectively. It also verified that the new algorithm can perform a high accuracy under the conical motion. 2011 IEEE.   A model of 1PN quasi-rigid body for rotation of celestial bodies 期刊论文  OAI收割 INTERNATIONAL JOURNAL OF MODERN PHYSICS D, 2003, 卷号: 12, 期号: 5, 页码: 811-824 作者:  Tao, JH;  Xu, CM 收藏  |  浏览/下载：17/0  |  提交时间：2012/08/08 rigid body  PN approximation  rotation  angular momentum
