Tracking control of a satellite formation.

摘要

Satellite Formation flying is a key technology for the space missions of the future, as a formation of a satellite will be doing the job as a single satellite with high precision and flexibility. The challenge facing this technology is in controlling the position and orientation of a different satellite with respect to a satellite which is the known as the master satellite of the formation of satellites. This work focuses on the tracking control of a controlled satellite, with respect to an uncontrolled leader satellite. Control is designed using Linear Quadratic Regulator (LQR) techniques. Simulations are performed using ODE solvers to propagate the dynamics of a follower satellite in the presence of J2 perturbation to a leader satellite. Planar dynamics has been considered in designing the control of the follower satellite.
