Abstract

We consider a continuous-time optimal control problem for a swarm of single thruster, single reaction wheel spacecraft aiming to reach a target formation. The dynamic model of each spacecraft is obtained by augmenting the Hill-Clohessy-Wiltshire equations with the coupled dynamics of the reaction wheel and thruster. For the optimal control problem, we penalize the deviation from the target formation, the overall fuel usage, and the fuel imbalance between agents. The optimal control law is then obtained by using the minimum principle to formulate a split-boundary-value ODE, which is then solved numerically. Numerical simulations for a simple swarm of three satellites show that the proposed approach successfully reduces the fuel consumption of the most fuel-intensive spacecraft, thus extending the overall lifetime of the formation system.

欠驱动卫星燃料平衡编队飞行控制
研究了单推力器、单反作用轮航天器群以到达目标编队为目标的连续时间最优控制问题。通过将Hill-Clohessy-Wiltshire方程与反作用轮和推进器的耦合动力学进行扩展,得到了各航天器的动力学模型。对于最优控制问题,我们对偏离目标编队、总体燃料使用和智能体之间的燃料不平衡进行惩罚。然后利用最小值原理构造了一个分边值ODE,得到了最优控制律,并进行了数值求解。一个简单的三颗卫星群的数值模拟表明,所提出的方法成功地降低了燃料最密集的航天器的燃料消耗,从而延长了编队系统的整体寿命。
