摘要:

针对推力器安装误差对卫星姿态控制产生强干扰的问题, 设计一种紧凑卫星推进系统的姿态控制算法. 采用对控制力矩和干扰力矩建模的方法对姿态控制影响进行分析, 得到最差情况下的推力器安装误差角组合. 通过计算机仿真实验, 对比了不同安装误差角下三轴的控制结果. 实验结果表明, 轨道机动模式下姿态控制算法具备包络最差情况的能力, 控制结果稳定, 满足精度要求.

关键词: 姿态控制, 推力器, 安装误差

Abstract:

Aiming at the problem that thruster fix error had strong interference on the satellite attitude, we designed a compact satellite propulsion system for attitude control algorithm. By modeling the control moment and disturbance moment, we analyzed the impact on the attitude control and got the thruster fix error angle combination in the worst case. We compared the control results of the three axis under different fix error angle through the computer simulation experiment. Experimental results show that attitude control algorithm has the capability of enveloping the worst case in orbit maneuver mode, and the control results are stable and meeting the accuracy demand.
