本文研究以滑块和滚转轴稳定条RSB(Roll Stabilizer Bars)作为执行机构的太阳帆航天器的姿态控制, 分析了姿态控制机构的物理模型, 利用欧拉方程建立了太阳帆的姿态动力学模型.针对此类模型, 设计了太阳帆航天器三轴姿态控制系统, 通过数值仿真研究了三轴姿态控制的短期响应特性.最后以中科院空间中心提出的SPORT(Solar Polar Orbit Radio Telescope)任务为背景, 研究了在轨道转移过程中太阳帆的姿态控制效果.仿真结果表明, 基于滑块和滚转轴稳定条控制的太阳帆能够满足大角度快速的姿态机动要求, 从而实现任务要求的目标轨道 |

In this paper, solar-sail attitude control system which employed moving masses for pitch/yaw trim control and roll stabilizer bars for roll control was studied.Physical model of solar-sail attitude control system had been analyzed, and the dynamical model was established using Euler's attitude dynamical equations.According to the model, a nonlinear PID controller was found to control the three-axis attitudes.Finally, a series of simulations, including the Solar Polar Orbit Radio Telescope misson's trajectory transfer, were run to determine the effectiveness of the attitude controller and characterize the behavior of attitude control method using moving masses and RSB |
