Virtual FDR Based on LS-SVM and Its Applications to Reconstruction of Control Surface Angular Deflection Signals

为重构操纵面偏角信号,提出了基于最小二乘支持向量机(LS-SVM)的虚拟飞行数据记录器设计.在设计中,LS-SVM被作为仿真器和重构器.仿真器用来模拟飞机的飞行动态特性,重构器用于来重构主操纵面偏转信号.仿真结果表明:本设计是重构操纵面偏转参数的强有力工具,在飞行事故调查中有非常广阔的应用前景.

For the reconstruction of Control Surfaces Angular Deflection （CSAD） signals, a scheme of Virtual Flight Data Recorder （VFDR）, which is based on Least Squares Support Vector Machines （LS-SVM）, is proposed. The scheme consists of LS-SVM Simulator （LS-SVMS） and LS-SVM Reconstructor （LS-SVMR）. LS- SVMS is used to simulate the flight dynamics of aircraft, and LS-SVMR to reconstruct the CSAD. The simulation shows that the scheme provides a powerful tool for reconstruction of CSAD and has a promising application to the investigation of aircraft crashes.
