摘要

针对火控系统结构复杂、故障信息获取困难、故障特征多的特点。提出了一种基于遗传算法优化BP神经网络的火控系统故障诊断方法。针对BP神经网络在运行过程中预测精度差,容易陷入局部极值的问题。为了获得更好的诊断效果,采用优势互补原理将遗传算法与BP神经网络算法相结合。利用遗传算法计算网络参数的初始值,优化初始权值和阈值,找到最优的隐层节点数。结合实例分析,与传统的BP神经网络相比,该方法在解决火控系统故障诊断问题中的准确性得到了提高。同时,验证了该方法在火控系统故障诊断中的有效性。

Fault diagnosis of fire control system based on genetic algorithm optimized BP neural network
In view of the complex structure of the fire control system, difficulty in obtaining fault information, and multiple fault characteristics. This paper proposes a fire control system fault diagnosis method based on genetic algorithm optimized BP neural network. For the problem of poor prediction accuracy of BP neural network in the operation process, and easy to fall into local extreme value. In order to obtain a better diagnosis effect, the principle of complementary advantages is used to combine genetic algorithm with BP neural network algorithm. The genetic algorithm is used to calculate the initial values of network parameters, optimize the initial weights and thresholds, and find the optimal number of hidden layer nodes. Combined with case analysis, the accuracy of this method is improved compared with traditional BP neural network in solving the problem of fire control system fault diagnosis. At the same time, it proves the effectiveness of the proposed method in fire control system fault diagnosis.
