摘要：
A method of patching between propulsion segment and glide segment is presented in this article, to optimize the flight control strategy of low thrust multiple gravity assist trajectories. Firstly, the optimization model of low thrust control strategy and the model of gravity assist are established based on the indirect optimization algorithm and B-plane theory. Secondly, the optimization model of low thrust multiple gravity assist control strategy is established under the given on-off time sequence. Besides, the genetic algorithm (GA) and sequential quadratic programming (SQP) algorithm are used to solve the optimization problem. Finally, the Earth-Venus-Earth-Jupiter low thrust transfer orbit control strategy is optimized as an example, to verify the correctness and effectiveness of the optimization model. It is shown that, the method presented in this paper can be used to optimize the control strategy of low-thrust multiple gravity assist trajectories. © 2019, Editorial Department of Control Theory & Applications.
