“…With the local coordinate system of each module and the global coordinate system of the LSS during assembly in Figure 2, the structural characteristics are studied using the finite element method. The concept of CU (Wang et al, 2019) is used to design the distributed controller. To consider the influence from other modules, each module and all its direct neighbors {G(I,:)} are treated as a CU.…”

“…Recently, many researchers have pointed out that on-orbit assembly is the most likely solution to this issue with support from various technologies of space robots and modular structure designs (Dorsey and Watson, 2016;Duan, 2018;She et al, 2019;Wang and Hou, 2014). Some preliminary results (Boning and Dubowsky, 2010;Gong and Macdonald, 2019;Wang et al, 2019) have clearly demonstrated that undesirable vibration may be excited when constructing the LSS, significantly influencing its orbit and attitude motion. It illustrates that the active vibration suppression is one of the most important technical issues to be solved for the LSS during on-orbit assembly (Duan, 2018).…”

“…The distributed control approach, based on the idea of transforming the global control into the local control, provides a new solution to the vibration control system design of the LSS. It has supposed that the distributed control units (CUs) are equipped and self-controlled with own actuators, sensors, and cooperative controllers (Wang et al, 2019), then the vibration control system could be easily adaptive along with the varying LSS through updating the distributed controllers during assembly. But the robustness and the online computation efficiency of distributed controllers are still limited by the controllers' form and the dimension of the unit's model.…”

Subject to the limited envelope size and carrying capacity of a rocket, it could be one of the most promising solutions to construct a large space structure through multilaunching and on-orbit assembly. Taking the antenna of the solar power satellite as the research objective, a novel vibration suppression strategy is developed in this article to guarantee high structural stability of the large space structure during on-orbit assembly. The concept of distributed control unit, together with the varying location relationship matrices, reflects the structural characteristics of the large space structure during on-orbit assembly. The explicit expression form of the control unit’s dynamic model is first derived based on the Newmark-β method. Then, the distributed adaptive model predictive controller is proposed to suppress the vibration of the large space structure aroused by weak impact among assembling modules. Through recalculating the control matrices efficiently at each assembly, the proposed controller achieves adaptive updating along with the varying large space structure. The feasibility of the proposed distributed adaptive model predictive controller is investigated in the numerical simulations, and the centralized fast model predictive controller is adopted for better comparison. The results demonstrate that the distributed adaptive model predictive controller can effectively suppress vibration of the large space structure during on-orbit assembly, with good adaptability, robustness, and computation efficiency.
