Hybrid Genetic Algorithm Collocation Method for Trajectory Optimization

摘要

In this Note, we presented a hybrid numerical optimization technique for synthesis of trajectories using a direct Hermite-Legendre-Gauss-Lobatto collocation technique. The minimum-time low-thrust transfer trajectory from a geocentric circular orbit to an areocentric circular orbit was computed. The initial guesses for the nonlinear programming problem were obtained by searching through the state space for feasible candidate solutions via a genetic algorithm with a shooting method. The results obtained compare very favorably with published results.
