چکیده

A new method is proposed for the experimental determination of the longitudinal and lateral hydrodynamic coef cients of a low-speed UUV. The technique presented is a development of the classical free-decay test. A body is excited with a mechanism of springs, and system identi cation techniques are carried out on measured data, with the intention of evaluating the added mass and linear damping of the body in decoupled longitudinal and lateral models. Simulated results are presented in order to estimate the potential accuracy of these new methods. Copyright c 2004 IFAC.

Identification of an Autonomous Underwater Vehicle Dynamic Using Extended Kalman Filter with ARMA Noise Model

In the procedure of designing an underwater vehicle or robot, its maneuverability and controllability must be simulated and tested, before the product is finalized for manufacturing. Since the hydrodynamic forces and moments highly affect the dynamic and maneuverability of the system, they must be estimated with a reasonable accuracy. In this study, hydrodynamic coefficients of an autonomous un...

Hydrodynamic Coefficients Identification and Experimental Investigation for an Underwater Vehicle

Hydrodynamic coefficients are the foundation of unmanned underwater vehicles modeling and controller design. In order to reduce identification complexity and acquire necessary hydrodynamic coefficients for controllers design, the motion of the unmanned underwater vehicle was separated into vertical motion and horizontal motion models. Hydrodynamic coefficients were regarded as mapping parameter...

تعیین ضرایب هیدرودینامیکی زیرسطحی‌ها به روش تست مدل

In recent years, unmanned vehicles have intensively been developed to reduce human dangers for marine applications. Predicting the hydrodynamic coefficients of an autonomous underwater vehicle is important during the vehicle’s design phase. In other words to design an AUV, one must clarify its maneuverability and controllability based on a mathematical model. The mathematical model contains var...
