航天器编队飞行构形保持与重构的继电型控制

研究小偏心参考轨道航天器编队飞行构形保持与重构控制的工程实现技术。首先给出相对运动状态转移矩阵,并推导出常推力控制情况下相对运动状态递推的解析表达式;进而给出脉冲推力、连续变推力和继电型推力三种发动机的推力模型和示意图。分别将等速度冲量的三种推力模型代入相对运动状态转移矩阵中,比较相同条件下相对运动控制作用效果的差异,理论推导结果表明:在一阶意义上,三种推力模型对相对运动控制作用等效,因而航天器编队构形保持与重构控制可以基于继电型推力模型来实现。

Bang-Bang Control for Maintenance and Reconfiguration of Spacecraft Formation Flying

In this paper,the enabling technique of maintenance and reconfigurati on control of spacecraft formation flying is studied.First,the state transfer matrix of relative motion was introduced and the expression of relative motion with constant thrust control was educed.Then,3 models of thrust were illustrated,which are impulse thrust,continuous thrust and Bang-Bang thrust.With the state transfer matrix,the differences of the thrust models in relative motion control were explored.Results show that in first order means the relative motion control effects with impulse thrust,continuous thrust and Bang-Bang thrust control are equivalent.So the problem of maintenance and reconfiguration of spacecraft formation flying could be implemented with Bang-Bang thrust control.
