Theory Study by CGM for Moving Force Identification
The conjugate gradient method (CGM) is proposed in this paper to improve the ill-posed problem of moving force identification.Based on theoretical analysis,the CGM formula is deduced and applied in moving force identification.Related research shows that the CGM have higher identification accuracy and robust noise immunity as well as producing an acceptable solution to ill-posed cases to some extent comparing with the time domain method (TDM),when they are used to identify the moving force.The theoretical study results by CGM are practical significant to selection properly method for moving force identification.
