The premise of the laser communication link establishment is the optical axis stabilization in airborne laser communication. In view of the greater optical axis stabilization error caused by the nonlinear perturbation of the communication terminal carriers and the unknown perturbation model,combined active disturbance rejection control and repetitive control,the active disturbance rejection algorithm compensated by repetitive control was proposed to completely eliminate the periodic steady-state tracking error. Compared with the adaptive PID control method,the simulation results show that the active disturbance rejection algorithm compensated by repetitive control can effectively restrain the nonlinear disturbance of the platform,improve the system steady-state accuracy and has faster response speed and stronger robustness.
