Hybrid Control with Thrusters and Reaction Wheels for Time Optimal Attitude Maneuvers of Spacecraft
위성자세 최소시간 거동을 위한 추력기와 반작용 휠 통합제어
Abstract
Time-Optimal solutions for attitude control with reaction wheels as well as with thrusters are studied. The suggested varying-time-sharing ratio thrusting is found to reduce the maneuvering time enormously. The hybrid control such as sequential hybrid and simultaneous hybrid with reaction wheels and thrusters are considered. The results show that simultaneous hybrid method reduces the maneuver time very much. Spacecraft model is KOrea Multi-Purpose SATellite(KOMPSAT)-II, which is being developed by KARI in KOREA as an agile maneuvering satellite.
