Outline
The unmanned platforms have the advantages of small size, low cost and no man-carrying operation, and are widely used in various military missions. At present, the unmanned platforms mainly use electric energy as power source, and their demand for reliable power transmission methods is increasing. In the cases where personnel cannot participate, the charging interfaces are not suitable, and the charging process is low in efficiency, wired charging or battery replacement has drawbacks, which cannot meet the demand for electric power transmission of the unmanned platforms. The system structure is designed to meet the requirements of unmanned platforms wireless power transfer, and based on this structure, a parameter optimization method based on particle swarm optimization (PSO) algorithm is proposed. By analyzing the structure and characteristics of the compensation circuit, coupling coil and energy storage device of the unmanned platform wireless power transfer system, the optimization objectives of the mathematical model of the system parameter optimization and the constraints of power, efficiency and current are proposed, and the algorithm flow of the parameter optimization method of the unmanned platform wireless power transfer system based on PSO algorithm is designed. The results show that the proposed optimization method based on PSO algorithm can reduce the fluctuation amplitude of the output voltage, power and efficiency with the load resistance and coupling coefficient change, and improve the robustness and environmental adaptability of the unmanned platform wireless power transfer system.
