| 摘 要： | 研究了大型卫星三轴大角度姿态机动控制。建立了以控制力矩陀螺作为执行机构的大型卫星姿态动力学方程,针对快速性和鲁棒性要求,设计了一种滑模变结构控制器。控制器基于反馈四元数,避免了源自三轴大角度机动欧拉角描述的奇异性,且滑动模态能满足Lyapunov意义的渐近稳定。仿真结果验证了该控制器的有效性和优良性能。

| Abstract: | The attitude maneuver control of large-scale satellite was studied in this paper.The dynamics model of satellite based on control moment gyro was built up.To meet the requirement of the high speed and robusticity,a sliding mode variable structure controller was derived.The controller was described by quaternion to remove the singularity coming from the large angle attitude maneuver.The sliding mode would satisfy Lyapunov stabilization.The simulation results showed that the proposed approach was effective an... |
