Abstract：The low transfer efficiency and poor robustness are important obstacles restricting the development of laser power transmission.The routing strategy of the network has been studied for efficient and reliable energy transfer.The paper analyzed the architecture of the laser power transmission network,modified the calculation formula of laser trans-mission efficiency in the atmosphere,and abstracted the network into a weight graph.Considering the multidimensional coupling characteristics in the laser power transmission network,a two-layer optimization strategy with spatio-temporal decoupling is proposed.The first layer optimization realizes path planning based on Dijkstra algorithm to find the most efficient energy transmission path.The second layer optimization is based on the optimal paths,takes the total loss as the objective function,builds mathematical models and solves it with inner iterative PSO algorithm.Through the simulation of a unmanned aerial vehicle(UAV)cruise system under different control strategies,the effectiveness and feasibility of the two-layer optimization strategy are verified.
