摘　　要：针对库仑力—太阳帆混合推进的航天器在行星悬浮轨道附近编队保持控制问题进行了研究.首先,建立了在行星悬浮轨道附近的航天器编队动力学模型,然后对模型进行线性化处理,推导出航天器编队相对运动方程.设计积分滑模编队飞行控制器,通过调节太阳光压力及星间库仑力对编队构型进行保持控制,具有响应速度快和对系统模型依赖小的特点.数值仿真表明存在扰动的情况下,该控制方法能实现行星悬浮轨道附近编队保持控制.The problem of maintaining control is investigated for the hybrid propulsion spacecraft formation around the planet-centered displaced orbit.Firstly,the dynamics model of spacecraft formation near a planetary suspension orbit is established,and then the relative motion equation of spacecraft formation is derived via linearizing the model.In terms of control strategy,an integral sliding mode formation flight controller is designed,which can maintain and control formation configuration via adjusting the size of solar pressure and inter-satellite Coulomb force.The controller has the characteristics of fast response and little dependence on system model.Finally,the numerical simulation shows that the proposed control method can achieve formation keeping control near the hovering orbit of the planet under the condition of disturbance.
