Simulation research on ATP system of airborne laser communication

Abstract

The compound axis tracking control circuits model of the ATP system was established and simulation was run on the tracking control performance of the ATP system. It was found through simulation that with the fixed coarse tracking error, the dynamic lag error in the coarse tracking servo system could be suppressed to 120μrad; and with the fixed fine tracking error, the dynamic lag error in the fine tracking servo system could be restrained to 2.73μrad, and the vibration residual could be controlled within 1.5μrad.
