摘　　要：针对静止轨道单太阳翼卫星在转移轨道段,太阳翼展开对日定向稳定控制过程中,太阳翼结构的初期放气干扰力矩对姿态影响的问题,利用卫星姿态动力学模型、姿态变化和推力器等参数,估计太阳翼放气产生的干扰力矩。通过理论仿真,验证了估计方法的正确性。以风云四号(FY-4)卫星为例,在轨实时估计结果表明:FY-4卫星太阳翼放气持续时间近11个小时,初期最大干扰力矩达37mN·m,比光压力矩约大2个量级,其对姿态影响不可忽视。文章的研究结果可为地面控制系统设计和在轨控制参数修改提供数据参考。During geostationary orbit satellite sun-oriented stability control process after solar wing deployed in transfer orbit,the influence on attitude of disturbance torque caused by initial air-bleed of solar wing cannot be ignored.In this paper,the disturbance torque is estimated using satellite attitude dynamics model,attitude change and the parameters of the thrusters.The theory imitates really and verified the accuracy of estimating the method.Through related parameters in-orbit of FY-4 satellite,the result shows that the air-bleed duration of FY-4's single solar wing lasted nearly 11 hours and the initial maximum disturbance torque is 37 mN·m,which is about 2 orders of magnitude larger than the solar pressure torque and the influence on attitude cannot be negligible.The estimation result is visual and believable,and can provide the basis for the design of control system on ground and the modification of control parameters in-orbit.
