Roto-Translational Control of Spacecraft in Low Earth Orbit Using Environmental Forces and Torques

In this paper, relative orbit and attitude adaptive controllers are integrated to perform roto-translational maneuvers for CubeSats equipped with a Drag Maneuvering Device (DMD). The DMD enables the host CubeSat modulation of aerodynamic forces/torques gravity gradient torque. Adaptive independent orbital revisited account traslational-attitude coupling while compensating uncertainty in parameters such as atmospheric density, drag/lift coefficients, location Center Mass (CoM) inertia matrix. Uniformly ultimately bounded convergence error states is guaranteed by Lyapunov-based stability analysis maneuver. A simulation example an along-track formation maneuver between two simultaneous control using only environmental forces torques presented validate controller.
