摘要

With the rapid development of the aerospace technology, more and more attention has been focused on the deep space exploration. The advantages of low-thrust spacecraft bring both benefits and challenges in space explorations. At one time,a few asteroids are selected to be explored by the means of energy relation and phase relation. As a typical NP-HARD problem, trajectory optimization has become the hot point in aerospace research. Considering the limitation of classical local optimization algorithms, variant global optimization algorithms for trajectory optimization are applied in lots of literature. Based on the parameters optimization of low thrust and impulse maneuver, this paper investigates the DE, PSO, GA algorithms and generates two hybrid algorithms. The results in this paper indicate the validity and feasibility of the hybrid algorithms.
