The servo control system of the optoelectronic tracking equipment usually is a kind of SISO. When the fast moving target is tracked
the over-tune of the servo system is the main representation for the dynamic tracking error. As the result
the tracking ability may be improved by limiting the over-tune. We put forward a method
the advanced position compensation (called as APC in short)
which is to check the speed-overtune by applying the advanced position information. For the large accelerate target
small over-tune tracking is achieved
but it lowers the ability for tracking the sine signal at low frequency area. While the dynamic high-type can improve the tracking precision for the sine signal at low frequency area
we work out a brand-new method
which combines the advantages of the both. It increases the tracking precision in the whole frequency band at large scale for the optoelectronic tracking system. The simulation results show that when the target moves with the largest accelerate 120/s2
120/s
the maximum static tracking error is about 0.6.
