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.   Cascadic multigrid methods for parabolic problems 期刊论文  OAI收割 SCIENCE IN CHINA SERIES A-MATHEMATICS, 2008, 卷号: 51, 期号: 8, 页码: 1415-1439 作者:  Du Qiang;  Ming PingBing   |  收藏  |  浏览/下载：22/0  |  提交时间：2018/07/30 cascadic multigrid method  parabolic problem  finite element methods  backward Euler scheme  smoother  stability  optimal error order  optimal complexity   A note on the quadrilateral mesh condition RDP (N,psi) 期刊论文  OAI收割 JOURNAL OF COMPUTATIONAL MATHEMATICS, 2007, 卷号: 25, 期号: 1, 页码: 27-30 作者:  Shi, Dongyang;  Shi, Zhong-Ci;  Wu, Jingzhu   |  收藏  |  浏览/下载：13/0  |  提交时间：2018/07/30 isoparametric finite element  optimal order error estimate  quadrilateral mesh condition   Nonconforming finite element analysis for a plate contact problem 期刊论文  OAI收割 SIAM JOURNAL ON NUMERICAL ANALYSIS, 2002, 卷号: 40, 期号: 5, 页码: 1683-1697 作者:  Han, WM;  Wang, LH   |  收藏  |  浏览/下载：20/0  |  提交时间：2018/07/30 nonconforming finite element method  elliptic variational inequality of fourth order  plate frictional contact problem  optimal order error estimate
