| Summary: | This paper examines a complete solution to autonomous formation flying of satellites where problems of position, velocity and attitude estimation, data fusion across the cluster, constrained actuators, fuel efficient manoeuvres and robustness are all considered. The joint problem of inaccurate state estimation combined with low thrust is addressed through the use of Kalman filter and an LP-solvable constrained predictive controller. Attitude control is ensured by a globally stable quaternion-based adaptive feedback controller. Calibration of control signals for translational force actuation is introduced. Options of solutions are analysed and the complete system and its system parts are illustrated in realistic simulations. |
