【摘要】：针对面向非合作目标的航天器相对轨道动力学系统,研究了基于视线制导的开关控制问题。详细推导了视线相对运动模型,并定性分析了重力差项。基于相平面法,分别独立设计了横向和纵向相对运动通道的开关曲线控制算法。针对横向控制,基于比例导引律设计了开关曲线,并利用李雅普诺夫方法给出了稳定性证明。针对纵向控制,采用双开关曲线,并给出了一种相应的设计方法。数值仿真分析验证了所提出的开关控制方法的有效性。
[Abstract]:For the relative orbit dynamics system of spacecraft facing non-cooperative target, the switching control problem based on line-of-sight guidance is studied. The relative motion model of line of sight is derived in detail, and the gravity difference term is qualitatively analyzed. The switching curve control algorithms of transverse and longitudinal relative motion channels are designed independently. For transverse control, the switching curves are designed based on proportional guidance law, and the stability proof is given by using Lyapunov method. The double switch curve is used and a corresponding design method is given. The effectiveness of the proposed switching control method is verified by numerical simulation.
