%X In this paper, we use
Port-Hamiltonian framework to stabilize the Lagrange <span style=\"font-family:Verdana;\">points in the Sun-Earth three-dimensional Circular Restricted Three-Body
Problem (CRTBP). Through rewriting the CRTBP into Port-Hamiltonian framework,
we are allowed to design the feedback controller through ener</span><span style=\"font-family:Verdana;\">gy-shaping
and dissipation injection. The closed-loop Hamiltonian is </span><span style=\"font-family:Verdana;\">a candidate of the Lyapunov function to establish
nonlinear stability of the designed equilibrium, which enlarges the application
region of feedback controller compared with that based on linearized dynamics.
Results show that th</span><span style=\"font-family:Verdana;\">e
Port-Hamiltonian</span><span style=\"font-family:Verdana;\"> a</span><span style=\"font-family:Verdana;\">pproach
allows us to successfully stabilize the Lagrange points, where the Linear
Quadratic Regulator (LQR) may fail. The feedback </span><span style=\"font-family:Verdana;\">system based on Port-Hamiltonian approach is also robust against whit</span><span style=\"font-family:Verdana;\">e
noise in the inputs.</span>
