In order to improve the stability of two-dimensional servo stability system in mobile laser communication equipment "communication in motion" environment, in this paper, gyroscope installation and correction optimization method, charge coupled device(CCD) centroid optimization algorithm, fast convergence of small values in the same direction of gyroscope and CCD and other methods are used to optimize the dynamic performance of the two-dimensional servo stability system. The optimized system is installed on a six-axis swing table to simulate the dynamic environment, so as to verify the stability of the servo stability system under the excitation conditions of different amplitudes and frequencies. The experimental results show that the receiving power variation range of the optimized system is significantly reduced, and the stability accuracy of servo system is improved by at least 27% under the same excitation condition.
