摘要： 首先利用交会对接固有动力学特性，施加第一脉冲推力使追踪器自动到达目标器位置；第二脉冲推力使两个飞行器相对速度降为零。这种控制称为双脉冲。该文根据双脉冲控制原理寻找燃料消耗最省的交会对接时间，最后还进行了大量数学仿真，比较各种初始条件下交会对接动力学特性和燃料消耗。

Abstract: n this paper,a simple and minimun-fuel control stratagy for space rendezvous by two impulses is presented. A first impulse is designed to produce an essentially coasting trajectory which intercepts the target at time T. At that time, a braking velocity increment (second impulse) is added in order to stop the relative motion. Fuel consumption is minimized by selecting the rendezvous time T. Finally, the dynamic characteristics of rendezvons and docking are analysed through mathematics simulation.
