传输线网络瞬态响应灵敏度分析方法

摘要

针对传输线网络瞬态响应灵敏度分析问题,提出了一种采用快速傅里叶变换的灵敏度分析方法.方法从描述整个传输线网络特性的电路方程出发,将传输线网络瞬态响应灵敏度转化为求解传输线网络瞬态响应以及网络参数矩阵对电路参数的偏导数,实现了传输线网络任意节点瞬态响应对任意网络参数的灵敏度分析.该方法无需对耦合传输线进行解耦,能够分析任意类型传输线及任意负载.算例结果表明,方法正确有效.%A new method sensitivity analysis based on FFT is proposed for the transient response sensitivity of transmission line network. Base on the circuit equations which can describe the characteristics of a transmission line network, the sensitivity analysis of the transmission lines network is predigested into calculating the transient response of the network and derivations of network parameter matrix in circuit parameters. All kinds of transmission lines and arbitrary load can be analyzed by this method without any complicated decoupled operatioa The experimental results show that the method is correct and effective.
