A Guidance Control Method for Lunar Hyperbolic Rendezvous with Rotating Space Station

针对面向环月旋转空间站的绕月双曲交会导引过程,提出一种多阶段导引控制方法。关于近程导引的设计,采用连续推力条件下相平面开关控制的方法进行制导。关于远程导引的设计,提出基于偏差演化线性近似法的脉冲修正控制方法,达到了远距离粗制导的目的。对可能存在的异面偏差扰动,采用一种阻尼振动形式的控制加速度进行异面偏差修正。仿真结果表明,该方法能够精准高效地解决面向旋转空间站的绕月双曲交会导引控制问题。研究结论可为降低载人月球探测任务运输成本提供参考。

Aiming at the lunar hyperbolic rendezvous guidance process of a rotating circumlunar space station,a multistage guidance control method is proposed.In terms of the design of short-range guidance,the method of phase-plane switch control with continuous thrust is adopted for guidance control.In terms of the design of long-range guidance,a pulse correction control method based on deviation evolution linear approximate is proposed to achieve the purpose of long-range rough guidance.For the possible disturbance of out-of-plane motion deviation,a control acceleration in the form of damped vibration is adopted to correct it.The simulation results show that the method can solve the guidance control problem of lunar hyperbolic rendezvous with the rotating space station accurately and efficiently.The research conclusion can provide reference for reducing the transportation cost of human lunar exploration missions.
