摘要
针对Halo轨道的留位控制问题,提出一种跟踪名义参考轨道的非线性最优跟踪控制策略。首先得到日-地系统第二平动点附近的有控制力作用下的轨道动力学方程,其次利用微分修正法得到要跟踪的名义参考轨道,然后将ASRE非线性最优跟踪控制方法与精细积分法相结合,针对Halo轨道的留位设计非线性控制器,最后利用数值算例验证了本文方法的有效性。
A new nonlinear optimal tracking control scheme is proposed to remain close to nominal paths for the station-keeping problem of Halo orbits. Firstly, the orbital dynamics equations with control force of the spacecraft near the second libration point of the Sun-Earth system are developed. Then the nominal orbits are obtained by differential correction process. In combination with the nonlinear optimal tracking control method based on the ASRE and precise integration method, the station-keeping controller of the Halo orbit is designed. The simulations illustrating the effectiveness of the nonlinear tracking controller are-performed.
