本文假设相对运动用Clohessy-Wiltshire方程描述,给出了确定将跟踪航天器转移至目标航天器速度轴上的对接口的时间最短、△V最小的轨道控制策略的方法。在控制律设计中着重考虑了安全问题。为了比较,首先研究了沿直线的强迫运动,接着指出线性优化方法可以计算广义最小△V和安全轨道控制策略,从而在跟踪航天器失控的情况下保护目标航天器免于碰撞。机动次数、允许的轨道区域以级推力大小的限制条件可以包含在方程的求解中。
This paper assumes that the relative motion is described by the Clohessy-Wiltshire equation and gives a method to determine the minimum or minimum ΔV trajectory control strategy for tracking the spacecraft to the interface of the target spacecraft. In control law design, the safety problem is considered. For the purpose of comparison, the forced movement along a straight line is first studied, and then the linear optimization method can be used to calculate the generalized minimum ΔV and safety trajectory control strategy to protect the target spacecraft from collisions when the spacecraft is out of control. The number of maneuvers, the allowable limit of the track area to the magnitude of the thrust, can be included in the solution of the equation.
