【摘要】 本文针对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。更多还原

【Abstract】 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.更多还原
