Abstract:

In this paper, station-keeping of heliocentric displaced orbits using a hybrid of solar sail and solar electric propulsion is investigated. In order to avoid the problem of low control precision and excessive dependence on model accuracy, which occurs when controllers are designed according to locally linearized models, a station-keeping control method based on active disturbance rejection control (ADRC) technique is proposed. Firstly, the dynamic model of a spacecraft using hybrid low-thrust propulsion in the heliocentric displaced orbit is derived based on the circular restricted three-body problem (CRTBP). Secondly, considering unmodelled dynamic and external disturbance, a station-keeping control method based on disturbance estimation and compensation is then presented. Finally, numerical simulations show that in the presence of system uncertainties, initial injection errors, and perturbations of the eccentric nature of the Earth's orbit, high station-keeping control precision can be achieved with relative small velocity increment.

Key words: hybrid low-thrust propulsion, solar sails, heliocentric displaced orbit, station-keeping, active disturbance rejection control
