Piezoelectric angular acceleration sensor is used to measure angular acceleration directly  Adaptive FIR filter based on LMS algorithm is established on DSP  by which angular acceleration signal can be filtered and corrected errors adaptively  then angular acceleration signals can be measured adaptively. This method avoids measurement errors and calculation noise by computing angular acceleration indirectly  thus improving measurement precision and making measurement results better than traditional methods. The gotten angular acceleration can be sent to servo control mechanism as feed forward control signals to improve control effects of servo turntable significantly. 2011 IEEE.   Feed-forward control to stabilize optical axis based on accelerometer (EI CONFERENCE) 会议论文 2010 International Conference on Computer, Mechatronics, Control and Electronic Engineering, CMCE 2010, August 24, 2010 - August 26, 2010, Changchun, China Wenfeng B.; Juan C.; Hu W. 收藏  |  浏览/下载：15/0  |  提交时间：2013/03/25 In the optoelectronic tracking system  the azimuth and elevation system determine the pointing precision of the optical axis. We discuss how to stabilize the optical axis by apply the feed forward control based on the accelerometer output. Both the acceleration and speed are applied to the compound controller. The experimental results show that when the azimuth servo system works at maximum speed 50/s and maximum accelerate 30/s2  the maximum tracking error of the system is 1.08'  with the feed forward compensation  so the precision is increased 6 times compared to that of without compound control. 2010 IEEE.   The research on servo control technology of O-E theodolite based on angular acceleration sensor (EI CONFERENCE) 会议论文 2010 International Conference on Computer, Mechatronics, Control and Electronic Engineering, CMCE 2010, August 24, 2010 - August 26, 2010, Changchun, China Wei L.; Jin G.; Juan C. 收藏  |  浏览/下载：13/0  |  提交时间：2013/03/25 A new servo control methods for O-E theodolite is presented in this paper. The methods integrates optimally feed forward and feedback control  and adopts acceleration delay compensation based on velocity delay compensation  then achieves servo control of O-E theodolite effectively. Furthermore  Angular acceleration sensor is applied as information resources  and adaptive filter is formed to provide with feed forward control signal in the methods. For double closed loop servo control system of O-E theodolite  the location correction loop and velocity correction loop are analyzed and designed. Simulation and experimental results show that comparing with traditional methods  this servo control methods can improve significantly tracking precision and stability of O-E theodolite. 2010 IEEE.
