| 摘 要： | 遗传算法是一种可以对包含多个连续变量的目标函数进行全局优化的算法。本文在一维频域理论互作用程序的基础上,采用遗传算法对螺旋线行波管的慢波结构进行了全局优化设计,提高了行波管的互作用效率。在单频点优化过程中,螺旋线分成三段的情况下,利用遗传算法优化了输出功率最大的最佳螺旋线长度,然后利用遗传算法对多段螺旋线问题进行了优化。为了满足带宽的要求,本文又利用高低端优化的方法对螺旋线行波管进行了带宽优化,得出了一组高效的满足带宽条件的螺旋线行波管慢波结构的制管参数。

| Abstract: | Genetic algorithm can globally optimize the objective function including more than one continuous variable.This paper globally optimized the slow-wave structure of helix TWT by using genetic algorithm based on one-dimensional frequency domain interaction program,and the electronic efficiency of helix TWT is improved.In the optimizing process on single frequency,the helix length is optimized to get the best output power by using genetic algorithm when the helix is divided into three sections.In order to meet... |
