摘　　要：研究了使用反作用推力作为执行机构的姿态控制系统 ,针对挠性飞行器姿态机动控制 ,给出了命令整形时间燃料优化设计方法 .在机动过程中 ,挠性振动对机动时间、燃料消耗和机动精度具有很大的影响 ,文中给出了挠性振动抑制手段 ,使机动完成的同时 ,振动得到有效抑制 ,由于振动频率和振动阻尼不易精确参数化 ,所以考虑挠性振动抑制设计方法对振动频率和振动阻尼的鲁棒性设计问题 。Attitude control system is studied using jet as actuator for flexible spacecraft. The time fuel optimal designing method, which named command preshaping, is investigated for the attitude maneuver control of flexible spacecraft. In the processing of maneuver, flexible vibration greatly influences the maneuver time, fuel and maneuver accuracy. The means of suppressing flexible vibration is provided so that the vibration is suppressed efficiency. Because the vibration frequency and damping is difficult to be parameterized accurately, the robust design problem of vibration frequency and damping is considered. Finally, the simulation result convinces the feasibility and validity of the method.
