Abstract: A multi-input multi-output direct-adaptive fuzzy predictive tracking control method for a satellite attitude system with parametric uncertainty and external disturbance is presented. First, a nonlinear generalized predictive controller is designed based on the satellite attitude model; then, a direct-adaptive fuzzy controller is constructed to approximate the unknown terms in the predictive control law caused by system model uncertainties. It is proved that the proposed controller can make satellite track the desired attitude trajectory and force the tracking error to converge to a small neighborhood of the origin. Simulation results show the effectiveness of the method.
