The paper proposes a new measurement method of angular acceleration for photoelectric servo turntable. 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.

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.

Space optical remote sensor is very important in many fields of science and military significance. It is widely applied. Space optical remote sensor design and manufacturing require precision and stability. Focusing mechanics is an important component of remote sensors. Focusing mechanics can guarantee the stability of the entire mechanics focusing accuracy
therefore the stability of research focusing mechanics is very important. In order to guarantee the space optics remote sensor focusing mechanics the stability
takes steps the space optics remote sensor focusing organization mechanics characteristic analysis from the classics contact theory. This article uses international general non-linear finite element analysis software ABAQUS to carry on mechanics characteristic analysis to the space optics remote sensor focusing mechanics. First acts according to the focusing mechanics unique feature
carries on the finite element to the structural model the grid division
the material attribute disposition and the boundary condition indeed grades. Then establishment contact non-linear finite element model
and to focusing organization finite element model infliction unit action. Like this contacts the result and the equivalent static analysis result which the nonlinear analysis obtains carries on the contrast and the analysis. This article last count result modality is 90HZ
satisfies the space optics remote sensor structure overall modality to request to be bigger than 50HZ.This article when carries on the dynamic analysis
extracts the structure kinetic energy and the acceleration curve. In the dynamic analysis obtained transient response analysis modality 70.5Hz
this also is bigger than 50HZ. The dynamic analysis indicated the structure dynamic stability has the distinct enhancement
has provided certain foundation for the space optics remote sensor following development work
reduced the overall system development cycle. 2009 SPIE.
