Attitude change control method, attitude change control system, attitude change control program and program recording medium

Disclosed is an attitude change control system that is designed to efficiently output a torque for attitude change of a space craft using CMGs and realizes a real time CMG driving rule. A CMG gimbal steering law generates target profiles for setting angle and angular velocity for each gimbal by applying an anisotropic weighted gradient method based upon the necessary torque calculated by a feed back controller and a feed forward controller from the angle and angular velocity in the target direction from the attitude navigator and the current angle and angular velocity of the space craft estimated by the attitude estimator as well as the current condition of each gimbal from the CMG , thereby controlling the CMG for changing the attitude of the space craft dynamics to the target direction.
