摘要:

针对弹用继电器的接触电阻预测和预测精度问题,提出了一种基于萤火虫算法(FA)优化改进灰色模型的新型灰色模型。在传统灰色GM(1,1)模型的基础上,运用等维灰数递补方法对模型进行动态更新建立改进灰色模型RGM(1,1),并引入萤火虫算法对其权值参数进行优化,得到新模型RFGM(1,1)。通过RGM(1,1)模型和RFGM(1,1)新模型预测了接触电阻变化趋势,经过对预测结果的对比分析,表明新模型具有较高的预测精度。

Abstract:

Aiming at the problem of contact resistance prediction and prediction accuracy of missile relays,a new gray model based on the firefly algorithm (FA) optimized and improved gray model is proposed.On the basis of the traditional gray GM(1,1) model,the model is dynamically updated using the equal-dimensional gray number recursive method to establish an improved gray model RGM(1,1),and the firefly algorithm is introduced to optimize its weight parameters,and get new model RFGM(1,1),the RGM(1,1) model and the RFGM(1,1) new model are used to predict the trend of contact resistance.After a comparative analysis of the prediction results,it shows that the new model has a higher prediction Accuracy.

Key words: firefly algorithm, grey model, contact resistance, relay, life prediction
