This paper studies a novel robust adaptive finite-time attitude tracking and synchronization control problem for multi-spacecraft with leader-following architecture, actuator saturation, unknown time-varying inertia and disturbance. Aiming at rejecting the influence of uncertainties and disturbances, an adaptive algorithm is proposed with no prior knowledge of inertia. Meanwhile, based on finite-time control, consensus algorithm and graph theory, a robust adaptive and synchronized attitude tracking control law with a dynamic adjustment function is presented to regulate the attitude to a common time-varying desired state in finite time and improve the dynamic property of system. The effectiveness and performance of the designed control approach are demonstrated through numerical simulation results.
