摘要
随着空间技术的发展,大型化、低刚度和挠性化已成为现代航天器发展的一个重要趋势。对卫星大挠性结构抑制技术地面试验系统进行了总体方案设计,建立了基于模态分析方法的挠性桁架的数学模型,并进行了比例积分微分控制律、全维观测器以及线性二次型调节器的设计与仿真,最后通过仿真验证了本文方法的有效性。
With the development of space technology,large-scale,low rigidity and flexibility have become an important trend in the development of modern spacecraft.The overall scheme design of ground test system for large flexible structure suppression technology of satellite is carried out,the mathematical model of flexible truss based on modal analysis method is established,and the design and simulation of proportional-integral-differential control law,full-dimensional observer and linear quadratic regulator are carried out.Finally,the simulation results verify the effectiveness of the proposed method.
