针对无人机机电系统结构内部战伤状态评估问题,提出了基于改进经验模态分解(Empirical Mode Decompo-sition,EMD)的战伤状态评估参数设计方案.首先分析了无人机机电系统典型战伤模式及损伤机理,提出了基于状态参数深层分析的状态评估方案;其次考虑到EMD端点效应对机电系统战伤状态评估带来不利影响,提出了基于多项式拟合延拓的EMD改进方案,基于改进EMD综合奇异值熵理论,构建了机电系统战伤状态评估参数设计方法.最后开展了仿真数值算例研究,结果表明本文所提能够有效的无人机机电系统战伤状态评估结论.
The Battle Damage Estimation Method of UAV Mechanical and Electrical System via Improved EMD
To estimate the battle damage results of the UAV mechanical and electrical system,an method of the battle damage estimation value was proposed with the improved EMD.Firstly,the typical battle damage types and mechanism of UAV mechanical and electrical system were analyzed,and the estimation programme was provided with data deep analysis.Then considering the adverse effect caused by the date end,the improved algorithm with polymerization fitting expanding was added in the EMD arithmetic,combining the improved EMD and singular value entropy,the battle damage state estimation value was proposed.Finally,the numerical example was given,and the simulation results demonstrate the effectiveness of the propsed method in this paper.
