Abstract
In this paper, maximum-likelihood (ML) and its relaxation algorithm, which are used to identify the mathematics model of an underwater vehicle(UV), are discussed. With the trial data of zigzag tests, the hydrodynamic derivatives of the UV were estimated, and the relaxation algorithm is confirmed to have better astringency from the contrast between the two methods. Then a simulation environment based on these parameters is established to verify the validity and effect of these methods. The result shows the model is credible and the methods are very useful for the research of maneuverability and adaptive control of underwater vehicles.
