Abstract:

A full six-degree-of-freedom computer model of the Naval Postgraduate School Autonomous Underwater Vehicle NPS AUV II is developed. Hydrodynamic Coefficients are determined by geometric similarity with an existing swimmer delivery vehicle and analysis of initial open loop AUV II trials. Comparisons between simulated and experimental results demonstrate the validity of the model and the techniques used. A reduced order observer of lateral velocity was produced to provide an input for an enhanced position estimator. Results are presented which show that the position estimator can be calibrated using AUV II run data to provide a real-time accurate estimate of position.
