Definition

The acceleration produced per unit mass under continuous thrust, serving as the control input for orbit maintenance. In the paper, the control input vector U=[U_x, U_y, U_z]^T represents three-axis control accelerations, applied to the velocity components of the dynamics through the input matrix B=[0_{3x3}; I_{3x3}]^T. Simulation results show the maximum control acceleration occurs at the initial time, on the order of 10^{-7} m/s^2 per axis, converging toward zero after stabilization.

Application Value

This class of orbits has significant application value in lunar mission site selection and space station deployment, providing spacecraft with a stable dwelling environment and favorable mission geometry.
