A Model Predictive Controller of Spacecraft Formation Tracking Based on the Hill Equation

Abstract:

Spacecraft formation flying has higher performance, higher reliability and lower costs comparing to the traditional single spacecraft. So it becomes a research hotspot in the field of aerospace in China and abroad over the past decade. This paper focuses on the orbital maintenance control between the following spacecraft and the main spacecraft. On the basis of circular orbit or nearly circular orbit, this paper studied the relative motion of spacecraft formation flying based on the Hill equation without considering the influence of the perturbation factor, when the distance between spacecrafts is close. This paper used the generalized predictive control method to design a controller of spacecraft formation tracking. By using Matlab/Simulink, the simulation results showed that the spacecraft has a good orbit tracking capability and a strong anti-interference ability.
