This article discusses the maintenance of an $L_1$-type artificial equilibrium point in the Sun–[Earth+Moon] circular restricted three-body problem by means of an electric solar wind sail. The reference configuration instability is compensated for with a feedback control law that adjusts the grid voltage as a function of the distance from the natural $L_1$ point. Two different control strategies are analyzed assuming the solar wind fluctuations to be modeled through a statistical approach.

电动太阳风帆人工共线拉格朗日点维护

这篇文章讨论了一个维护 $L_1$型人工平衡点在太阳-[地球+月球] 圆形限制三体问题通过电动太阳风帆。参考配置的不稳定性通过反馈控制法则进行补偿，该法则将电网电压调整为与自然环境距离的函数。$L_1$观点。假设通过统计方法对太阳风波动进行建模，分析了两种不同的控制策略。
