摘要
针对挠性航天器振动抑制中的作动器优化配置问题,综合考虑闭环系统的可控度和作动器的电缆长度,提出一种新型的复合优化指标,在完成振动抑制的同时,有效缩减作动器电缆长度,减小航天器能量损耗及电磁干扰;在此基础上,采用遗传算法,完成作动器安装位置的快速寻优。采用实际尺寸的挠性帆板有限元模型,通过大量的数值仿真,验证了所提方法的有效性。
For the vibration suppression problem of a flexible spacecraft,a new composite performance index is presented to optimize the placement of actuators.The controllability of vibration control system and the length of cable are simultaneously considered in the proposed performance index.Furthermore,a simple genetic algorithm is involved to find optimal solutions within a short computational time.Numerical simulations verify the effectiveness of the proposed approach.
