中文摘要：
使用小推力控制可以得到许多独特的非自然卫星编队构型,主从星相对位置不变和从星圆形匀速绕飞构型是两类最典型的构型,建立了这两类编队构型的编队参数（主从星距离、空间方位和绕飞速度）与一天内燃料消耗的关系。进一步考虑存在初始误差时控制律的设计,指出PD控制律能够维持小初始误差编队构型,改进的PD控制律能够维持中等初始误差编队构型,而PD控制律和直接法相结合的混合控制律能够维持大初始误差编队构型,仿真结果验证了所设计控制律的有效性。
英文摘要：
Many special non-natural formation configurations can be obtained by applying low-thrust.Constant relative position configuration and circular constant velocity fly-around configuration are proposed as two typical formations.The relationship between formation configuration parameters（relative distance,space orientation and fly-around velocity） and fuel consumed in one day is established in this paper.Furthermore,the design of control law for non-zero initial error configurations is considered.It is proved that the PD control law could maintain formation configurations with small initial errors,a modified PD control law could maintain formation configurations with medium initial errors,and a hybrid method combined with the PD control law and direct method could maintain formation configurations with large initial errors.Simulations show that the designed control law is valid.
