Abstract EN
This paper presents a robust controller with an extended state observer to solve the Synchronous Fly-Around problem of a chaser spacecraft approaching a tumbling target in the presence of unknown uncertainty and bounded external disturbance.
The rotational motion and time-varying docking trajectory of tumbling target are given in advance and referred as the desired tracking objective.
Based on dual quaternion framework, a six-degree-of-freedom coupled relative motion between two spacecrafts is modeled, in which the coupling effect, model uncertainties, and external disturbances are considered.
More specially, a novel nonsingular terminal sliding mode is designed to ensure the convergence to the desired trajectory in finite time.
Based on the second-order sliding mode, an extended state observer is employed to the controller to compensate the closed-loop system.
By theoretical analysis, it is proved that the modified extended-state-observer-based controller guarantees the finite-time stabilization.
Numerical simulations are taken to show the effectiveness and superiority of the proposed control scheme.
Finally, Synchronous Fly-Around maneuvers can be accomplished with fast response and high accuracy.
