基于多核LS-SVR的航电设备剩余寿命预测

Avionics Remain Life Prediction Using Multiple Kernel LS-SVR

航空电子设备是飞机系统的重要组成部分,其故障率占全系统故障总数的比例越来越高,对系统性能的影响越来越突出。论文提出了一种基于多核LS-SVR的预测模型,并用于某航电装置的剩余寿命预测。仿真结果表明,该多核LS-SVR模型与传统LS-SVR相比,具有更高的精度,是一个切实有效的电子设备寿命预测方法。

Avionics equipments are important parts of the aircraft system, and their failure probability is higher and higher, which will affect the performance of the whole system. A prediction model based on MKLS-SVR is proposed in this paper and used for remain life prediction with an avionic device. The simulation results show that the MKLS- SVR has a higher accuracy, comparing with the traditional model LS-SVR, and it is a practical and effective elec＇ tronic equipment life prediction method.
