利用拉格朗日方法推导了飞行器编队飞行的精确动力学模型，考虑了非线性项和J2项对飞行器编队模型精度的影响，利用自适应方法，在线评估J2摄动项对飞行器编队相对运动的影响。基于李雅普诺夫理论的非线性自适应控制，保障了在未知空间摄动影响下飞行器编队相对位置跟踪误差的全局渐近稳定。仿真结果显示：新的动力学模型能够准确描述飞行器编队飞行的相对运动。从而减少模型误差引起的燃料消耗。

Euler-Lagrange method is used to derive an accurate model for aircraft formation flying. The effects of nonlinearity and J2 on the accuracy of spacecraft formation model are considered.Adaptive method is used to estimate the effects of the bounded perturbation, such as the main disturbance J2 .The Lyapunov-based adaptive control method can guarantee the global asymptotic stability of spacecraft forma-tion relative position tracking error in the influence of unknown perturbations.The simulations show that the new dynamic model can exactly describe the relative motion of aircraft formation, and will reduce the fuel consumption resulted from model error.
