Station-Keeping for Earth-Moon Solar-Sail Resonant Libration Point Orbits
摘要
This chapter investigates a dynamical reshaping control method for the station keeping of unstable resonant periodic orbits using the solar radiation pressure in the solar-sail-augmented Earth-Moon Quasi-Bicircular Problem. The control strategy aims to reshape the geometrical structures defined by the unstable Floquet modes, furthermore, asymptotic stability can be achieved by incorporating the central Floquet modes into the procedures. The control variables considered are the attitude angles of the sail, including two scenarios, one with the ligthness number of the sail being constant and another one being variable. The nominal point definition also plays a role in the stability and convergence rate, but independently of this fact, the Jet Transport technique enables the control laws to be developed in a unified way. In addition, the controllers are obtained as Taylor polynomials in terms of the deviation between the state of the spacecraft and the nominal point.
