The current control of the breech pulsed power cables and the stability of the total current are important factors which have an influence on the performance of the electromagnetic railgun system. In order to achieve these two targets, a two-objective optimization model through the genetic algorithms and weighted combination method is established. An optimization example of 20-mm railgun with 1-MJ fixed energy storage is given. The results show that the methods can be satisfied to the optimization design under the following premises. The reference value for the mean square error of the pulsed power cable peak current which represents the degree of the current control is selected between 1.5 and 4 kA, and the reference value of the compression ratio which represents the stability of the total current depends on the average compression ratio of the initial population. The mean square deviation of the best individual can be reduced to 600–750 A, and the compression ratio can be increased to 0.64–0.68 when the peak value of the total current is limited between 500 and 560 kA.

电磁轨道炮脉冲电缆电流控制优化

后膛脉冲电力电缆的电流控制和总电流的稳定性是影响电磁轨道炮系统性能的重要因素。为了实现这两个目标，通过遗传算法和加权组合方法建立了双目标优化模型。给出了具有 1-MJ 固定能量存储的 20-mm 轨道炮的优化示例。结果表明，在以下前提下，该方法可以满足优化设计。代表电流控制程度的脉冲电力电缆峰值电流均方误差的参考值选择在 1.5 到 4 kA 之间，代表总电流稳定性的压缩比参考值取决于初始种群的平均压缩比。当总电流峰值限制在500～560 kA之间时，最佳个体的均方偏差可降低到600～750 A，压缩比可提高到0.64～0.68。
