Research output: Contribution to journalArticlepeer-review


The problem of stabilizing the motion of a spacecraft in an unstable orbit around the interior Sun-Earth libration point (L1) is addressed in this paper. Modern control techniques, which extend the traditional H framework to periodic discrete linear time-varying systems, are employed in the solution of the problem. Nonlinear simulation results are presented and it is shown that the control effort required can be provided by next-generation electric propulsion systems.
