This paper deals with the problem of attitude tracking control of rigid satellite subject to control input saturation and parametric uncertainty. An adaptive controller is designed to implement real-time identification for inertia parameters, and Lyapunov stability theory is utilized to achieve the stability analysis. By introducing hyperbolic tangent saturation function into the control scheme, it can be concluded that the control input saturation problem can be effectively restrained so long as the control parameters are selected to satisfy a specific inequality. Numerical simulations are included, and the results demonstrate that the control scheme realizes the attitude tracking control under control saturation and implements identification for inertia matrix.
