A generalized predictive control with adaptive fuzzy estimator (GPC-AFE) is proposed for spacecraft. Model uncertainties and mismatch disturbances are considered in the process of controller design. For the attitude subsystem, a predictive control based on an adaptive fuzzy estimator is designed to deal with the unknown disturbances. For the angular velocity subsystem, the actual control input is designed by using the generalized predictive control. The derivative of virtual control and unknown disturbances in the actual control are also estimated by using an adaptive fuzzy estimator. With the proposed generalized predictive control, the tracking error of the attitude converges to a bounded neighborhood of the reference attitude. Theoretical results are illustrated by numerical simulation.
