基于交会概念研究了卫星在三维空间的最省燃料有限推力轨道转移问题。假设有一个飞行器已经在目标轨道上运动，此飞行器称为虚拟卫星。只要控制真实卫星与虚拟卫星软交会，就实现＊了真实卫星向目标轨道的转移。假定发动机推力大小为常值，方向可调。提供了真实卫星的相对运＊动动力学模型，用Ｐｏｎｔｒｙａｇｉｎ极大值原理导出了最省燃料的推力控制策略，建立了状态和共轭状态的初始边界条件。导出的两点边值问题由牛顿代方法求解。仿真结果验证了所提供方法的有效性。
Based on the concept of rendezvous, the most province-limited fuel orbit transfer problem of satellites in three-dimensional space was studied. Assuming that an aircraft is already moving on the target orbit, the aircraft is called a virtual satellite. As long as the control of the real satellite and virtual satellite soft fair, to achieve a real satellite to the target orbit transfer. Assuming the engine thrust size is constant, the direction can be adjusted. The relative dynamics model of the real satellite is provided. The Pontryagin maximum principle is used to derive the most fuel-efficient thrust control strategy, and the initial boundary conditions of states and conjugates are established. Derived two-point boundary value problem is solved by Newton’s method. The simulation results verify the effectiveness of the proposed method.
