摘要: 针对导弹制导控制系统电子设备密集、各性能特征参数间相互耦合关联性强、使用传统最小二乘支持向量机(LS-SVM)预测精度不高的问题,通过分析特征参数的时间相关性与空间相关性,对传统LS-SVM进行了改进,并利用D-S证据理论在数据融合中的优势,将传统与改进的LS-SVM进行融合,建立了联合最小二乘支持向量机(ULS-SVM)预测模型。以导弹制导控制系统为例,实现了关键参数预测。结果验证了模型的合理性与有效性。

Abstract: For intense electronic equipment in missile guidance and control systems, coupling relationship among feature parameters and low prediction accuracy of traditional least squares support vector machine(LS-SVM),the traditional LS-SVM is improved by analyzing the temporal correlation and spatial correlation of feature parameters. Traditional LS-SVM and improved LS-SVM are fused by taking advantage of D-S evidence theory. An unification of least squares support vector machine(ULS-SVM)prediction model is established. The key parameters are predicted by taking missile guidance and control systems as an example. The results show that the proposed ULS-SVM prediction model is rational and effective.
