摘要
Abstract
Space microgravity combination is an upgraded version of the tethered satellite system , a more powerful and prospective version for future applications .However ,both the systems are beset with the same problem : if there is no preset control ,the system′s motion is unstable. Therefore ,an effective control algorithm has to be developed to make the system stable .Based on a simplified dynamic model of tethered satellite ,the relationship between microgravity and dynamic inertia forces was used to deduce a very unique range rate control algorithm to stabilize the system concisely and productively .This algorithm can be applied to mass‐distributed ,elastic and other more complex cases of tethered satellite control .It can also be successfully adopted to control in‐orbit rendezvous and docking missions of the space microgravity combination .关键词
