Depth and Trim Control of an AUV

Damon Michael Vizl

Abstract


The use of Autonomous Underwater Vehicles in the field of underwater research and maintenance has driven the development of a prototype vessel at the University of New South Wales Australian Defence Force Academy campus. The aim of this design project was to investigate an alternative method of trim and depth control in order to minimize power consumption and address additional recommendations outlined in Nicholas Gover’s paper Optimum Design of a Small Underwater Vehicle: Small White Design and Build. The design methodology followed an iterative approach in order to enhance the use of feedback in the development of software packages and physical design. The method chosen to control trim and depth was to alter the buoyancy of the vessel, this method allowed for minimal weight calibration, decreased power consumption and internalized the mechanism to increase water tight integrity.
