Feed-forward control to stabilize optical axis based on accelerometer
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
