The objective of this study is to establish the high accurate pointing control method of the satellite with CMG while taking a photograph of the ground target. In the method, after the satellite starts to maneuver, the frequency of the CMG internal disturbance is estimated by the adaptive observer of Kreisselmeier. After the maneuver of satellite is finished, the active internal disturbance accommodation filter based on the internal model principle is performed and thereby the internal disturbance is eliminated by feedforward control. From the simulation results, it was confirmed the usefulness of the proposed method.
