先进上面级数字逻辑姿态控制律设计

摘要

Established Advanced Upper Stage (AUS)' attitude dynamics model and thrust' configured project.Based on the assignment request of quick,Lange-angle and exactitude attitude maneuver,and designed numeral logic control law.Advised attitude angle and attitude angular velocity's connection and the exist of measure error,measured off attitude phase plane to multi control areas,in order to save fuel and avoid the influence of measure error.Used actual AUS's parameters for attitude maneuver control,the simulation displayed using numeral logic control law could achieved pitch axis' s 60°attitude maneuver in 16 seconds,and could ensured attitude's pointing precision and attitude's stability.%建立了先进上面级姿态动力学模型和推力器配置方案,根据快速大角速度精确姿态机动的任务要求,设计了数字逻辑姿态控制律.考虑姿态角和姿态角速度的相互关系和测置误差的存在,将姿态相平面划分为多个控制区域,以节省燃料和避免测量误差的影响.在实际上面级参数下进行姿态机动控制仿真,采用数字逻辑姿态控制律能在16s内实现先进上面级俯仰角60°的大角度姿态机动,并能很好地保证姿态指向精度和姿态稳定度,控制效果也优于脉冲宽度调制.
