Abstract: The tracking accuracy and stability of servo system for the periscope laser communication terminal can be reduced by the torque pulsation of the internal actuator and the external disturbance during the establishment of communication link. In order to improve the anti-interference ability and tracking performance of servo system,the speed smoothness of servo system is improved by lowering the torque fluctuations of performing structure.The stability and dynamic tracking process of the system were tested and analyzed,and the effectiveness of the control strategy was verified through the dynamic tracking experiments of terminal control system. The experimental results show that the combined tracking precision of azimuth axis and elevation axis is within 2 μrad under the condition of platform disturbance with the maximum velocity of 0.131°/s and the maximum acceleration of 0.137°/s2 and 0.329°/s2. The jitter suppression ability and dynamic tracking performance of communication terminal servo system are verified through the experiment.
