During the process of acquisition, tracking and pointing in laser communication among satellites, the precision pointing mechanism is subjected to disturbances from the satellite platform as well as parameter uncertainties within the precision pointing system. Considering the parameter uncertainties, an uncertainty model of the voice coil actuators based fast steering mirror (VCA-FSM) is established. Based on the uncertainty model, an adaptive disturbance rejection control method is proposed, which utilizes gyroscope inertial measurements. The effectiveness is evaluated using simulation studies.
