Abstract

The relative position tracking and attitude synchronization control problem during the process of spacecraft tracking maneuver is addressed in this paper. A robust adaptive sliding mode controller developed on the Special Euclidean Group SE(3) is proposed to guarantee that the spacecraft tracks a prescribed trajectory in the presence of model uncertainties and external disturbances. The mass and inertia of the spacecraft are estimated and the controller adapts to the measurements, so that it is applicable without exact prior knowledge of the model parameters. The closed-loop system is proved to be almost globally asymptotically stable by employing Lyapunov's stability theorem. Finally, simulations for a given scenario are performed to show the performance of the controller.
