Considering the unstable of spacecraft trajectories around the Sun-Earth liberation points, a new station keeping strategy based on variable time intervals is presented and simulated in this paper. With this method, three different kinds of optimization strategies are conducted and a new performance measure form based on errors is also proposed to obtain a better control strategy which can minimize the system sensitivity of various types of uncertainty. Simulation results are introduced to demonstrate the effectiveness of the proposed methods.
