Abstract :
This paper investigates a distributed coordination control scheme using terminal sliding mode for formation flying spacecraft with coupled attitude and translational dynamics. A six Degree-of-Freedom (6DOF) coupled model in Euler-Lagrange form is established. A continuous controller is proposed to alleviate the chattering phenomenon of a terminal sliding mode control. Theoretical analysis shows that the controller can guarantee the finite-time stability of the overall closed-loop system.
