This paper is concerned with the problem of attitude stabilization of rigid spacecraft in the presence of parameter uncertainty and external disturbance generated by some time varying uncertain exosystems. A time varying internal model that is free of the uncertain parameter is proposed to compensate the disturbance. An adaptive attitude controller is presented by incorporating tune varying dynamic coordinate transformation, semi-tensor product and adaptive control method. Especially, the parameter uncertainties caused by the inertia matrix and uncertain exosystems are tackled by combining the semi-tensor product and adaptive control method. Finally, a simulation example is presented to illustrate the effectiveness of the proposed method.
