提出了一种能够使一组相同的航天器获得给定构型的卫星路径规划技术。该技术利用基于行为的方法，利用有限的感官信息，实现对相对几何形状的自主和分布式控制。每个卫星的期望速度被定义为来自一般高层行为的不同贡献的总和。通过称为平衡成形的反动力计算进一步定义了这些行为。我们表明，只考虑三种不同的行为，就有可能获得许多有趣的形成，我们描述了找到整个集合所需的理论框架。我们发现，通过允许有限数量的通信，该技术也可用于形成复杂的晶格结构。介绍并讨论了几种能够跟踪期望速度的控制反馈。我们的结果表明，滑模控制特别适合于与所开发的技术相结合。
We present a satellite path-planning technique able to make a set of identical spacecraft acquire a given configuration. The technique exploits a behavior-based approach to achieve an autonomous and distributed control over the relative geometry, making use of limited sensorial information. A desired velocity is defined for each satellite as a sum of different contributions coming from generic high-level behaviors. The behaviors are further defined by an inverse-dynamic calculation dubbed equilibrium shaping. We show that by considering only three different kinds of behavior it is possible to acquire a number of interesting formations, and we describe the theoretical framework needed to find the entire set. We find that by allowing a limited amount of communication the technique may be used also to form complex lattice structures. Several control feedbacks able to track the desired velocities are introduced and discussed. Our results suggest that sliding-mode control is particularly appropriate in connection with the developed technique.
