摘　　要：对于地球同步轨道的电推进卫星,可采用双机械臂式电推布局进行轨道维持控制.本文研究了双机械臂式电推布局的自主位保控制策略,针对南北各一台机械臂,每台机械臂分别配置一台电推力器的布局方式,通过每天1~2次点火,以尽量少的点火指向变动实现东西/南北联合位保控制.在双侧机械臂、电推力器正常情况下研究具有解析形式的在轨位保算法.研究基于单侧矢量调节机构和该侧电推力器的故障位保策略,给出衡量不同矢量机构能力和推力比冲下的位保效率衡量方法.仿真结果表明,正常/故障情况下的位保控制精度均能够满足同步轨道位保控制要求.本算法为解析形式,计算量较小,可以实现多星共轨和定点捕获/轨位漂移,便于量上自主实施.For electric propulsion geosynchronous satellites,orbit station-keeping can be carried out by electric propulsion layout with double robotic arms,and each robotic arm is equipped with one electric thruster.In this paper,a parsing-oriented approach is used to orbit station-keeping,and the East-West/North-South Station-Keeping maneuver is achieved by firing 1~2 times a day.The ignition direction remains unchanged for several days.Firstly,the station-keeping algorithm with analytical form is studied under the normal condition of double arms and thrusters.Then,a failure scheme based on the single arm with only one electric thruster is researched.Finally,a method to measure the efficiency of different vector mechanism capability and thruster specific impulse is given analytically.The simulation results show that the control accuracy can meet the requirements for geosynchronous satellites station-keeping,multi-GEO satellites collocation and fixed-point orbit injection.
