A propellant-free hybrid propulsion control scheme combining solar sail photon pressure and Lorentz force induced by Jupiter's magnetic field is proposed in this paper to address the two-spacecraft formation flying problem in near-Jupiter orbits.It is assumed that two equal-mass solar sail spacecraft operate on near-Jupiter circular orbits,where the chief spacecraft is electrically neutral and the deputy spacecraft carries controllable net electric charge.First,under the assumption of Jupiter's central gravitational field,a linearized relative motion dynamic model in the LVLH coordinate frame is established based on the Hill-Clohessy-Wiltshire equations.Considering the distinctive dynamic environment of near-Jupiter orbits,linearized correction terms accounting for Jupiter's strong non-spherical gravitational perturbation and Lorentz force terms derived from the tilted dipole magnetic field model of Jupiter are further incorporated.The solar sail light pressure difference is treated as a 3-dimensional continuous control input,while the charge-to-mass ratio of the deputy spacecraft serves as an auxiliary scalar control input,forming a complete state-space model for hybrid propulsion.Analysis reveals that the proposed hybrid control strategy can overcome the underactuated limitation of Lorentz force control alone and achieve full-state controllability for formation configuration maintenance.This work delivers a novel propellantless control paradigm for deep-space solar sail formation missions.
