The two-dimensional thermoelectric models of singlejunction and triple-junction GaAs solar cells are established respectively utilizing Sentaurus-TCAD, to investigate the damage effects caused by HPMs. Simulation results demonstrate that there are two burnout mechanisms of GaAs solar cells: damage caused by Joule heat accumulation under high electric field, and failure due to temperature surges induced by avalanche breakdown. In addition, fitted empirical formulas also show that burnout caused by Joule heat accumulation at the inflection point of the cathode front surface field occurs when the frequency of injection is above 3GHz, and damage energy decreases as the frequency increases. In contrast, the avalanche multiplication effect in the reverse-biased space charge region near the back-surface field can be triggered when the frequency is below 3GHz, and damage energy rises as the frequency rises. Besides, due to the enhancement of heat dissipation and the drop in avalanche ionization rate, the multi-junction GaAs solar cell becomes more difficult to burn out than the single-junction solar cell under the same HPM interference. Moreover, an equivalent model (based on the carrier mobility distribution when the injected HPMs signal does not reach the burnout threshold) is rebuilt to study the soft damage effect on the performance of GaAs solar cells, as caused by the injection of HPMs.

“…Simplified scheme of the multi-rotary joint solar power satellite antenna (Hou et al, 2015). Each module's assembly procedure is a complex process that requires the cooperative efforts of multiple space robots to facilitate transportation and docking process (Cheng et al, 2016). The on-orbit assembly mission here refers to the last docking process that the modules are slowly maneuvered to the assembly location by the assembly arms or robots, and the structural stability here refers to the structural stability of the whole assembled antenna.…”

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.

This paper investigates the on-orbit maintenance task planning of large-scale space solar power station. The research is of great significance for the normal operation of large-scale space equipment. Space robots are very maneuverable, which makes space maintenance possible. A new task planning algorithm is proposed for the on-orbit maintenance of space robots. Firstly, based on the discretization method, the modified clustering method is used to cluster the maintenance area of large-scale space solar power stations. Secondly, the hierarchical structure principle is used to assign tasks to the space robot, the inner layer plans the shortest path within the cluster set, and the outer layer plans the optimal path between the cluster sets. Finally, based on the optimal path of the outer layer of the maintenance task, a hybrid optimization algorithm based on tabu algorithm and modified ant colony algorithm is proposed. The algorithm can meet the space machine task allocation requirements and analyze the maintenance path under certain energy conditions. The simulation results show that the proposed algorithm can effectively solve the optimal problem of space robot mission planning under resource constraints. INDEX TERMS Space robot, task clustering, hybrid optimization algorithm, task planning.
