摘　　要：针对电子安全系统在高频通断变化下产生的传导电磁干扰噪声源阻抗提取问题,提出一种结合散射参数法和免疫算法的新方法。与传统散射参数法相比,新方法将提取误差控制在5%以内,显著提高了精度。与散射参数法结合梯度下降法相比,新方法通过免疫算法优化,将提取效率提升了68%,同时保持了5%以内的误差控制,有效解决了局部最优问题,增强了参数解的稳定性和收敛性。实验结果证实了新方法在阻抗提取的准确性和稳定性方面的优势,可为滤波器设计提供有效的指导。To address the issue of conductive electromagnetic interference(EMI)noise source impedance extraction in electronic security systems under high-frequency switching conditions,a novel method that integrates scattering parameter(S-parameter)analysis with an immune algorithm was proposed.Compared to the traditional S-parameter method,the method significantly improved accuracy by controlling the extraction error within 5%.In contrast to the S-parameter method combined with gradient descent,which enhanced extraction efficiency by 68%,while maintaining the error control within 5%,effectively addressed the issue of local optima and enhancing the stability and convergence of parameter solutions.Experimental results confirmed the superior accuracy and stability of the new method in impedance extraction,providing effective guidance for filter design.
