摘要
研究了一种采用混合执行机构的姿态单轴快速机动的控制方法。设计了由平行构型单框架控制力矩陀螺(SGCMG)和飞轮组成的混合执行机构配置方案。综合姿态机动规划,设计了前馈和反馈相结合的姿态机动控制律,并通过执行机构动力学分析给出了操纵律。仿真结果表明:采用平行构型SGCMGs和飞轮的混合执行机构模式,可实现姿态三轴高精度稳定控制和侧摆快速机动的任务要求。
An approach for fast monaxial maneuver using mixed actuators for salellite＇s attitude conlrol was studied in this paper. A configuration scheme of mixed actuators was designed which was composed of parallel mounted SGCMG and momentum wheel. A control law integrating feed-forward and feedback was designed for attitude maneuver based on the attitude maneuver path planning. The steering law was designed according the kinetic analysis of actuators. The simulation results showed that the mixed actuators control strategy could satisfy the requirement of triaxial stable control with high precision and fast skew maneuver.
