Abstract: For the satellite with rapid orbit or attitude maneuver ability,its inertia changes greatly with the fuel consumed in orbit,and consequently the mass parameters appear to be uncertain.For the flexible satellite with inertial matrix unknown,the attitude tracking control problem was solved.Considering the target angle rate changing,an adaptive attitude tracking control law was designed based on the error quaternion,and the corresponding close system stability was also proved.The numerical simulation results show the effectiveness of the proposed adaptive control strategy for the satellites with inertia unknown.

Key words: Flexible satellite, Attitude tracking control, Adaptive control, System stability
