| Abstract: | An optimal control problem based on universal variable is studied.Based on the dynamics equations with the orbital nonsingular elements,perturbation equations including universal variable for solving conic orbit are established.The optimal control problem of the equations is solved using Gauss pseudospectral method.At last,example of orbital transfer with zero inclination is computed and simulated.The simulation results demonstrate that the equations established and the Gauss pseudospectral method used in t... |
