High-precision three-axis detumbling and pointing attitude control strategy for a class of complicated space systems

We looked at the recent state-of-the-art investigations in the area of attitude control to propose a new three-axis detumbling and pointing strategy. The outcomes, organized along with Lyapunov-based approach, are to deal with a class of complicated space systems with a focus on unmanned spacecrafts with the different specifications. The responsibilities of the proposed control strategy are especially twofold, while the first one is to cope with the space system under control in the three-axis detumbling mode and the second one is to cope with the same system in the three-axis pointing mode. In a word, the detumbling mode control approach has to first be realized to control the unwanted angular rates oscillations in the three axes in the process of the separation of the space launcher system. The pointing mode control approach has to then be realized to track the profile of referenced rotational angles in the same three axes with respect to time. The improvements acquired in the present research are to introduce new Lyapunov-based approaches that are in support of the stability criteria, realized in both detumbling and pointing techniques, which are compatible with the unmanned spacecraft. The results indicate that the proposed Lyapunov-based approaches are appropriately handled via a series of experiments with different scenarios, in a short span of time. The approach performance is finally verified through the consideration of a set of potential benchmarks in the area of the system controlled.
