空间相对悬停轨道在空间操作中具有重要的作用。提出了一种相对圆轨道目标星任意位置的悬停闭环控制方法,并基于李雅普诺夫方法设计了反馈系数,解决了由于Hill方程线性化误差导致开环控制难以保持悬停效果的问题。实验结果表明,在服务星上增施加少量的额外燃料,可以实现服务星相对目标星长时间、高精度、稳定的悬停,并通过数值仿真验证了该方法的有效性。
Spatial relative hovering tracks play an important role in space operations. A closed-loop closed-loop control method is proposed for arbitrary target position relative to a circular orbit. Based on the Lyapunov method, a feedback coefficient is designed to solve the problem that it is difficult to maintain the hover effect due to the linearization error of the Hill equation. The experimental results show that adding a small amount of additional fuel to the service star can achieve high precision and stable hovering of the service star relative to the target star, and the effectiveness of the method is verified by numerical simulation.
