英文摘要

      The aspect ratio of solar-powered unmanned aircraft vehicles (UAVs) increases with the improvement of cruise duration. UAVs with large aspect ratio are not conducive to rapid deployment. This paper proposes an energy-saving connection control based on communication decision for solar-powered UAVs. The strategy created a method for determining the connection sequence, which achieves the purpose of connecting multiple small or medium-sized solar-powered UAVs into a larger and more energy-efficient UAV. First, the extended Kalman filter is used to estimate the state of the UAVs. Secondly, the information entropy is used to evaluate the situation and adjust the flight path and speed of the UAVs. Finally, the real-time connection process of the virtual UAVs is demonstrated by simulation. The research results show that connecting the UAVs in the optimal connection order can significantly reduce the final energy consumption of the formation. The situation-aware communication strategy can effectively reduce the communication frequency and optimize the formation control of the formation.
