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。
A control method of single-axis rapid maneuvering with hybrid actuators is studied. A hybrid actuator configuration scheme consisting of parallel configuration single frame control moment gyroscope (SGCMG) and flywheel was designed. In the integrated attitude maneuver planning, the attitude maneuver control law combining feedforward and feedback is designed, and the manipulative law is given through the dynamic analysis of the actuator. The simulation results show that the hybrid actuator model with parallel configuration SGCMGs and flywheel can realize the task of high-precision three-axis attitude control and rapid maneuvering of side swing.
