| 摘 要： | 研究帆板驱动影响下的卫星姿态控制问题.帆板驱动时存在转速波动,从而影响卫星姿态.在已有帆板驱动模型的基础上,分析帆板转速特性,通过对帆板转速的离线拟合和在线估计,结合卫星姿态动力学模型,设计了卫星姿态的一般前馈补偿和自适应前馈补偿控制器.数学仿真结果表明,两种前馈补偿控制均能有效克服由帆板驱动不平稳而造成的对星体干扰,实现卫星姿态高精度控制.

| Abstract: | The attitude control of a satellite under the influences induced by solar array driving is studied in this paper.There exists a fluctuation of driving speed of solar array,so the attitude is affected due to the coupling function.Based on the model of solar array driving issued before,the driving speed of solar array is analyzed.Then through offline fit and online estimation,combining with the attitude dynamics model,an attitude control with normal or adaptive feed-forward compensation is designed.Simulation results demonstrate that this two feed-forward controllers can overcome the disturbance caused by the rough driving of solar array and,as a result,the high accuracy attitude control can be achieved. |
