The Hamiltonian Structure-Preserving Control and Some Applications to Nonlinear Astrodynamics

Journal of Applied Mathematics, 2013
A systematic research on the structure-preserving controller is investigated in this paper, including its applications to the second-order, first-order, time-periodic, or degenerated astrodynamics, respectively.
