The mathematical model of AUV's maneuvering motion is reconstructed based on the hydrodynamic coefficients derived from the VPMM test.LS-SVM is adopted for analysis of the AUV's free-running model test results,and the hydrodynamic coefficients are identified.By comparing the identified parameters with those obtained by VPMM(Vertical Planar Motion Mechanism) test,the validity of LS-SVM in identifying the AUV's motion parameters is proved.The verification of the mathematical model demonstrates the validity of identified hydrodynamic coefficients.This method is very useful for the research of maneuverability and adaptive control of AUV.
