Abstract: The six degree-of-freedom coupling control of the chaser relative to the uncontrolled tumbling satellite with system uncertainties and external disturbances is studied in this paper. Initially, a non-linear six-degree-of-freedom coupled integrated dynamics model is established in the chaser's body coordinate system, which transforms the hovering control problem into relative position and relative attitude control problems. Then, an adaptive fuzzy sliding mode controller is designed based on the principle of fuzzy approximation. The controller can effectively overcome the uncertainty of the system model and the influence of external disturbance, eliminating the traditional chattering problem. The fuzzy adaptive law is derived from the Lyapunov method and the stability of the closed-loop system is proved. Numerical simulations verify the effectiveness of the proposed adaptive fuzzy sliding mode controller.

Key words: uncontrolled tumbling satellite, hovering control, fuzzy sliding mode control, adaptive control, six degree-of-freedom coupling
