The problem of launch vehicle vertical landing is divided into dynamic descent phase and vertical landing phase to solve. Firstly, a uniform time discrete SOCP method combined with continuous relaxation technique is adopted to solve complicated nonlinear trajectory optimization problems. Then, the LGL polynomial zeros point is used to discretize the second-order cone programming and improve the solution efficiency. By selecting few LGL polynomial zeros and piecewise Lagrange interpolation, the original problem is transformed into a parameter optimization problem, and the control input of the interpolation point is obtained. The guidance accuracy and adaptability of different methods is compared.
