| Abstract: | 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. |
