空间太阳能电站及其动力学与控制研究进展

Solar energy is a kind of rich, clean, and renewable energy, which has the potential to alleviate the energy crisis and environmental problems of the world. Due to the high energy density in space without the influence of weather and nighttime, an important way to obtain large amounts of solar energy in the future is to construct space solar power stations (SSPSs). However, the dynamics and control of the SSPSs are challenges to scientists and engineers, because SSPSs are ultra-large and ultra-flexible spacecraft that operate for decades with accurate attitude pointing requirement. The main purpose of this paper is to review the main results on conceptual designs, dynamics, and control of SSPSs. Firstly, the background and development history of SSPSs were briefly introduced. Meanwhile, the main conceptual designs of SSPSs were summarized. Then, the dynamic and control studies of SSPSs during their serving period were outlined, including dynamic modelling methods, effects of space perturbations, numerical simulation methods, orbital and attitude control, and structural vibration control. It is found that the studies of dynamics and control of SSPSs are still at the initial stage. The previous researches mainly focused on the simplified dynamic models of the SSPSs, such as rigid bodies, beams, and plates. Another focus is on the control of orbit, attitude, or structural vibration of SSPSs separately, despite the coupling effects among them. Nevertheless, the coupled orbit-attitude-structure models in space environment and coordinated orbit-attitude-structure control still need further developments. Finally, some future directions on dynamics and control of SSPSs were given.
