Testing of the Autonomous Microconductivity-Temperature Vehicle and a Direct Technique for the Determination of Turbulent Fluxes with Autonomous Underwater Vehicles
نویسنده
چکیده
Our immediate objectives are to develop a technique to measure vertical water velocity and the turbulent fluxes of heat and salt with Autonomous Underwater Vehicles (AUV), and to construct a vehicle to fully test and exploit the technique. This has been done in a limited way with our Autonomous Conductivity and Temperature Vehicle (ACTV). Morison and McPhee (1998) use the vertical motion of the ACTV as a proxy for the vertical motion of the water through which it moves. The key elements of the new technique are to use all available vehicle guidance data and account for the dynamics of the vehicle in the estimation of vertical water velocity. A new small AUV called the Autonomous Micro-conductivity and Temperature Vehicle (AMTV) has been built for proving the technique, and test data was gathered at the Surface Heat Balance of the Arctic (SHEBA) station in 1998.

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...
