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.   Applying observer feedback in motor control (EI CONFERENCE) 会议论文  OAI收割 3rd International Conference on Measuring Technology and Mechatronics Automation, ICMTMA 2011, January 6, 2011 - January 7, 2011, Shanghai, China Huan Z.-Y.; Li H.-W. 收藏  |  浏览/下载：11/0  |  提交时间：2013/03/25 When the speed is low or the encoder has a low precision  speed measured by backward difference method has obvious truncation error. This will arise ripple in the control system speed response. Speed filtering can decrease the ripple  but it's not good enough  and it also induces lag. A speed feedback method based on all-state observer was introduced to improve the speed feedback performance. Experiment results show that  compared to filtering method  the control system performance is improved.
