Zusammenfassung:PROBLEM TO BE SOLVED: To provide an attitude change control system capable of efficiently outputting the torque and realizing the real-time CMG (Control Moment Gyro) driving rule when changing the attitude of a space craft using the CMG. SOLUTION: Based on the required torque calculated by a feedback controller 13 and a feedforward controller 14 using the angle and the angular velocity in the target direction from an attitude profile calculator 12 and the present angle and the present angular velocity of a space craft estimated by an attitude estimation unit 11 and the present state of each gimbal from the CMG 40, the target profile for setting the angle and the angular velocity of each gimbal is generated by a CMG gimbal target profile generator 15 by an anisotropic weighted gradient method, the CMG 40 is controlled, and the attitude of a space craft dynamics 50 is changed to the target direction.
