摘　　要：灵犀03星是银河航天研制发射的国内首颗使用面积超过20 m^(2)柔性太阳翼的平板卫星,相比于传统卫星,一方面柔性太阳翼振动会给姿态控制系统带来低频扰动,另一方面卫星采用单翼非对称结构使得所受的干扰力矩是常规卫星的50倍以上.针对灵犀03平板卫星结构和布局的特点,设计一种融合低通滤波PID控制器(PIDT)与结构滤波器相结合的姿态控制器,该控制器以频带隔离为基础,降低太阳翼模态频率处的响应,保证控制精度的同时抑制太阳翼振动,仿真结果表明,该控制器可实现姿态控制精度0.03°(3σ),稳定度0.005(°)/s(3σ)的指标要求.Lingxi-03 satellite developed and launched by Galaxy Aerospace is the first flat panel satellite with a flexible solar wing of more than 20 square meters.Compared with traditional satellites,the vibration of flexible solar wings will bring low-frequency disturbance to the attitude control system.Additionally,the satellite adopts a singlewing asymmetrical structure to make the interference torque more than 50 times that of conventional satellites.According to the characteristics of the structure and layout of the Lingxi-03 flat panel satellite,an attitude controller combining PIDT and structural filter is designed,which is based on frequency band isolation.The response at the modal frequency of the solar wing is targeted to suppress the vibration of the solar wing to ensure the control accuracy and suppress the vibration of the solar wing.The simulation results show that the controller can achieve the attitude control accuracy of 0.03°(3σ)and the stability of 0.005(°)/s(3σ).
