基于 ICA 的动态测量误差分解重构方法
Dynamic Measurement Error Decomposition and Reconstruction Method Based on ICA
摘要
Abstract
The method that ICA was used to decompose and reconstruct dynamic measurement er-rors was researched.The basic algorithm of ICA to decompose and reconstruct dynamic errors was elabrated detailedly.A measuring device for dynamic measurement errors was built by using the coor-dinate measuring machine and dual-frequency laser interferometer.The dynamic error separating ex-periments were done.The dynamic error data was processed respectively by using the method of adaptive filtering,wavelet analysis and ICA,which was aimed to separate and reconstruct the system-atic errors with linear change and with periodic change and the dynamic random errors.The experi-mental results prove that the overall sample of the measured dynamic errors must be fully applied for the precise analysis and error component indentification of the measured dynamic errors.Compared with the previous two methods,the systematic error with linear change and with periodic change and the dynamic random error can be separated and reconstructed more effectively and accurately by using ICA.关键词
