In this paper  mathematic model and computer control strategy for optical electrical tracking system have been researched and discussed. First  the system's structure and its work process have been analyzed. Second  according to the system's moving law  the system's mathematic model has been built. As to the computer control strategy  trigger guiding  two closed loop PID control method as well as compound control method have been applied to satisfy the tracking accuracy. Third  we apply the bilinear transformation to get the digital system  and the sample time is 800Hz. The simulation results indicate that the maximum tracking error can be limited to less than 0.5 and the regulator time can be 0.04s. Then the control project resonance frequency should be more than 200Hz and the sample frequency should be more than 400Hz to meet the control accuracy requirement. So we can conclude that the system indexes such as swiftness  high accuracy as long as real time have been satisfied. And the requirement of mechanical property has been present which is very useful to mechanical working. 2011 IEEE.

A non-linear light-of-sight(LOS) locating compensation algorithm for certain aerial remote sensor is presented in this paper. The LOS locating system is composed of two main components  which are an inertial reference frame to provide coarse LOS locating and a 2-axis Fast Steering Mirror to remove the frame's residual error. The azimuth and elevation of LOS are both affected by the FSM two-degree-of-freedom rotation  which should be dealt with to raise the accuracy of LOS location. This paper extrapolates LOS locating algorithm of FSM by coordinate transformation  and gives corresponding deviation analysis for different LOS poiting angles. It is found that the angle deviation grows rapidly with range of FSM's travel enlarging  so the deviation must be eliminated. Through the data analysis for deviation  a non-linear compensation algorithm is proved effective to reduce the error of LOS significantly. Taking LOS changing in [-3 deg  3 deg] as an example  two analytic expressions are given  and the LOS locating accuracy rises by 34 times compared with non-linear compensation unused  and the cross coupling of LOS loating is 0.08%. 2011 IEEE.
