飞机颤振模态参数辨识试验的快速滤波算法
A Fast Filtering Algorithm in the Aircraft Flutter Modal Parameter Identification Experiment
摘要
Abstract
This paper,studied the optimal filtering estimation problem of the actural input and output sequences in the aircraft flutter modal parameter identification experiment.Based on the matrix factor decomposition from matrix theory and conditional expectation formula from statistical signal processing,an efficient recursive filtering algorithm was proposed.It is an innovation based approach that relies on the triangular decomposition of block Toeplitz matrices.We derived the esti-mation error and covariance expression about the estimation of the filtered input and output sequences.Finally in the simula-tion,we applied the filered input and output sequences to be the observed signals,which were used in the aircraft flutter mo-dal parameter identification experiment.Then we can obtain the more accurate transfer function and the modal parameters.关键词
