摘要
文中研究对象是带有太阳电池阵和天线等大挠性附件且太阳电池阵驱动的对地观测卫星.抑制太阳电池阵和天线挠性振动及太阳电池阵驱动对星体姿态影响是系统设计的目的.为此,选用带宽隔离法、坎值滤波器法对附件振动进行抑制;同时,针对卫星特殊飞行姿态所导致的通道间惯性耦合,设计了解耦算法给予解决;设计了具有低通滤波特性的外环修正回路,消除惯性基准单元的漂移误差及安装误差.将设计结果应用于对象模型并加入所有误差源后,进行仿真验证,系统设计结果满足给定的指标要求并有较大裕度.
The design of an earth observation satellite system with big flexible accessories, such as the solar panel and antenna, and driven by the solar panel, is to suppress the influence of the solar panel drive and flexible vibrations of the solar panel and antenna on the attitude of the satellite. The bandwidth insulation method and a notch filter were employed to suppress the accessory vibration. Aiming at the interchannel inertia coupling resulted from the special satellite attitude, a decoupling algorithm was designed to solve it. Outerloop correction with lowpass characteristic was designed to eliminate the drift error and alignment error of the gyro. The simulation was performed by applying the design result to the object model and taking all error resource into consideration. The result verifies the feasibility of the system design.
