Abstract
In this paper, we consider the attitude tracking and disturbance rejection problem of rigid spacecraft subject to a class of nonharmonic periodic disturbances generated by nonlinear exosystems, which can not be handled by linear internal model. A nonlinear internal model is designed to deal with such disturbances. Numerical simulations illustrate the performance of the proposed control algorithms.
