PROBLEM TO BE SOLVED: To provide a vehicle attitude control system which has high accuracy and responsibility, is inexpensive and small in size and saves power.SOLUTION: A two-stage vehicle attitude control system includes a first attitude control module having two momentum wheels, each momentum wheel comprising a restrictive movement two-axis gimbal which pivots the momentum wheel along two shafts out of three shafts of a vehicle. Further, the vehicle attitude control system includes a controller which is connected to the first attitude control module and a second attitude control module having plural reaction wheels which are located in a pyramid geometry in order to control vehicle attitude along at least one control axis common to control axes of two momentum wheels. The controller is so configured as to rotate the vehicle about at least one shaft among three shafts of the vehicle by adjusting operations of the first attitude control module and the second attitude control module.SELECTED DRAWING: Figure 1
【課題】精度、応答性が高く、廉価、省電力で小型なビークル姿勢制御システムを提供する。【解決手段】二段ビークル姿勢制御システムは、2つのモーメンタムホイールを有する第1姿勢制御モジュールを含み、各モーメンタムホイールは、ビークルの3つの軸のうちの2つに沿ってモーメンタムホイールを枢動させる限定移動2軸ジンバルを備える。また2つのモーメンタムホイールの制御軸と共通の少なくとも1つの制御軸に沿ってビークル姿勢制御を行うために、ピラミッド型に配置された複数のリアクションホイールを有する第2姿勢制御モジュールと、第1姿勢制御モジュール及び第2姿勢制御モジュールに接続されるとともに、第1姿勢制御モジュール及び第2姿勢制御モジュールの動作を調整して、ビークルの3つの軸のうちの少なくとも1つにおいてビークルを回転させるように構成されているコントローラと、を含む。【選択図】図1
