本文首次将带惯性权重的多目标量子粒子群(WMQPSO)算法应用到空间行波管慢波结构优化中。仅以提高电子效率为目标优化时,电子效率提高了6%,但非线性相移变大;以提高电子效率和减小非线性失真为目标时,电子效率提高了约3%,同时非线性相移降低了15°。实验结果表明,联合优化有效地改善了电子效率和非线性相位失真,优化结果显著。
For the first time, this paper applies the multi-objective quantum particle swarm optimization (WMQPSO) algorithm with inertia weight to the optimization of the SWT structure. The electronic efficiency was improved by only 6%, but the nonlinear phase shift became larger when the target was only optimized for improving the electron efficiency. The electron efficiency was improved by about 3% with the goal of improving the electron efficiency and reducing the nonlinear distortion, and the nonlinearity The phase shift is reduced by 15 °. The experimental results show that the joint optimization effectively improves the electron efficiency and nonlinear phase distortion, and the optimization results are significant.
