摘要
针对挠性航天器本身大范围刚性运动和携带载荷进行动态变形运动的耦合问题,建立一种动力学刚性-柔性耦合模型运动控制方法。该方法通过计算航天器所受的惯性力来推导挠性梁等效弯曲刚度,建立一个物理意义明晰并且耦合度低的动力学模型,能够全面分析对挠性梁的各种耦合干扰影响。仿真结果表明,建立的刚性-柔性耦合动力学模型能够对挠性梁进行全面控制分析,并通过调整相关参数有效控制耦合干扰项对挠性梁振动的影响。
Regarding the couple problem of flexible spacecraft＇s large category movement and load＇s dynamic transformer movement,a rigid-flexible controller includes craft,flexible beam and load is designed.In this design,the inertia-force is used to compute rigid and dynamic model is set up which has lower couple and physics meaning,which consider all couple disturbs roundly and restrain the interferential effects. The simulation result shows that setting up a whole craft-flexible beam-load system can analyse flexible beam working process roundly and can restrain couple interference clearly with some parameters adjusted.
