摘要
针对磁耦合无线电能传输系统中谐振回路参数配置困难,出现传输效率与输出功率难以兼顾的问题,以同时提高系统输出功率和传输效率为目标,通过对影响系统功效的传输频率、传输距离、负载阻值进行研究,构建了多目标优化模型,采用改进型多目标灰狼优化算法对模型进行求解,并通过模糊综合评估法对Pareto解集进行质量评价,得到可以满足使用需求的系统输出功率和传输效率参数值最优解。仿真实验结果表明,改进型多目标灰狼优化算法可以使发射端和接收端产生强耦合谐振,实现系统功效的优化。
Aiming at the difficulty in the configuration of resonant circuit parameters in the magnetic coupling wireless power transmission system and the difficulty in taking into account the transmission efficiency and output power,a multi-objective optimization model was established by studying the transmission frequency,transmission distance and load resistance that affect the system power and efficiency.The improved multi-objective gray Wolf optimization algorithm was used to solve the model,and the quality of Pareto solution set was evaluated by fuzzy comprehensive evaluation method,and the optimal values of system output power and transmission efficiency parameters were obtained.The finite element simulation results show that the improved multi-objective gray wolf optimization algorithm can make the transmitter and receiver generate strong coupling resonance,and realize the optimization of system efficiency.
