Abstract
A decoupling attitude control algorithm based on adaptive robust control method is proposed for spacecraft in the presence of external disturbances and uncertainties of moment of inertia. Firstly, the spacecraft model is divided into three independent loops for respective controller synthesis and the adaptive method is adopted as a compensation for the parameters uncertainties. Secondly, regarding the external disturbances and the adaptive compensation errors as composite disturbances, the robust control law is used to attenuate the effect to ensure that the attitude tracking errors is kept within a desired range. Finally, the validity and effectiveness of the proposed method for the spacecraft attitude control are well testified via numerical simulation results.
