| 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。

| Abstract: | 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 t... |
