Outline of Final Research Achievements

In recent years, faster attitude control of satellites has been demanded. This research proposes a highly efficient utilization of a variable speed controlled moment gyro (VS-CMG) to achieve high-speed attitude maneuvor for small satellites. In this research, we proposed and verified a method to effectively utilize torque that is wasted in conventional devices, and developed and demonstrated an very small attitude control device that is considered to be particularly effective for small satellites. Through this research, control laws for efficient operation of VS-CMGs were completed and control was demonstrated using ground test equipment.

Academic Significance and Societal Importance of the Research Achievements

衛星の高速姿勢変更は例えば大規模災害時などにいち早く災害エリアの観測を行うために，衛星の姿勢を大きく・高速に変更するために必要不可欠な技術となる．本研究により開発された制御装置及び制御則を小型の衛星に適用することにより，多くの小型衛星が高速に姿勢変更が可能となり，災害情報の迅速な把握や通信等が実施できるようになる．将来的にはより小型なデバイスを実現することにより，超軽量の柔軟部材などの形状安定に寄与させることも可能であり，安価軽量の宇宙構造物の構築などにも寄与できる．
