The invention discloses a long-term autonomous low-fuel-consumption accompanying flight method for a spacecraft, and the method comprises the steps: S1, setting accompanying flight parameters, setting an initial far-floating mode, an initial near-floating mode and a free-floating flight control mode of the spacecraft, when the spacecraft initially enters an accompanying flight state, if the spacecraft is not close to an accompanying flight boundary, entering the free-floating flight control mode, and if the spacecraft is not close to the accompanying flight boundary, entering the free-floating flight control mode; if the unmanned aerial vehicle is close to the accompanying boundary, entering an initial far-floating mode or an initial near-floating mode, and then converting into a free-floating control mode; s2, carrying out accompanying tangential control; s3, accompanying radial control is carried out, wherein the relative speed of the z axis of the orbit system is adjusted; and S4, carrying out accompanying flight normal control, wherein the accompanying flight normal control comprises adjusting the relative speed of the y axis of the orbit system. The method has the advantages that an on-satellite autonomous open-loop control mode is adopted, a spacecraft can carry out long-time low-fuel-consumption accompanying flight on a target satellite in a given accompanying flight area by setting an accompanying flight boundary value and related control parameters, and the service life of the spacecraft can be greatly prolonged.

    本发明公开了一种空间飞行器长期自主低燃耗伴飞方法,该方法包含:S1、设定伴飞参数,设置空间飞行器的初始飘远模式、初始飘近模式和自由飘飞控制模式,当空间飞行器初始进入伴飞状态时,若其未靠近伴飞边界,则进入自由飘飞控制模式,若其靠近伴飞边界,则进入初始飘远模式或初始飘近模式,进而转为自由飘飞控制模式;S2、伴飞切向控制;S3、伴飞径向控制,其包含对轨道系z轴相对速度进行调整;S4、伴飞法向控制,其包含对轨道系y轴相对速度进行调整。其优点是:该方法采用星上自主的开环控制方式,可通过设定伴飞边界值和相关控制参数,使空间飞行器在给定伴飞区域内对目标星进行长时间的低燃耗伴飞,可大幅提升空间飞行器的使用寿命。
