摘要
为保证微波无线传能系统具有可靠且高的传输效率,针对系统中发射天线存在的馈电相位误差,提出了一种基于最差情况分析的多准则优化设计方法。首先,推导了发射天线电性能参数与随机馈电相位误差的数学关系。其次,基于最差情况分析方法,建立了馈电相位随机误差的缩减区间描述模型。然后,提出了一种具有鲁棒性的波束收集效率优化设计方法。最后,通过蒙特卡洛方法验证了所提方法的有效性。
To ensure a microwave wireless power transmission system with both high reliability and high efficiency,a multi-criteria optimization design technique based on the worst case sensitivity analysis was developed.First,the relationship between the electrical performance of the transmitting antenna and the random excitation phase errors is formulated.Next,a reduced tolerance range model of the excitation phase based on the worst-case sensitivity analysis is established.Then,a robust excitation phase optimization design method is proposed to ensure high and reliable beam collection efficiency.Finally,the effectiveness of the proposed method is verified by the Monte Carlo method.
