| Abstract: | The optimization methods for asteroids spacecraft trajectory were summarized in this paper. The direct shooting method, collocation method, orthogonal collocation and differential inclusion in direct method, and indirect method were introduced. The advantages and disadvantages, and the application in the optimization for asteroids spacecraft trajectory of the methods were analyzed. The genetic algorithm, simulated annealing, particle swarm optimization, ant colony algorithm and multi-objective aggressive algorithm in intelligent optimization algorithm were also introduced. The advantages and disadvantages relative to the tradition optimization method, and some corresponding improved methods were analyzed. |
