Abstract

In this paper, an adaptive control algorithm is presented to enable a spacecraft to track desired trajectories near the L2 Lagrange point in the Sun-Earth system. An adaptive full-state feedback control law, designed using a Lyapunov-type analysis, exhibits globally asymptotic position tracking in the presence of the unknown spacecraft mass. The control law is simulated for a Lyapunov orbit in the vicinity of the L2 Lagrange point as the periodic reference trajectory.
