چکیده

With 900 Autonomous Underwater Vehicles (AUVs) required over the next decade (Newman et al., 2007) existing survey-style AUVs need improved utilization factors. Additional control devices to extend operational capability need consideration together with the interchange between AUV control approaches. This paper considers supplementary through-body tunnel thruster control during the transition from survey operation to low-speed manoeuvring. Modified manoeuvring equations permit investigation of energy level demands as a positively buoyant AUV is slowed down from cruising speed to maintaining a stationary position. A suitable model of the selected thruster device is proposed following a literature review of tunnel thruster performance.

Investigation of Hydrodynamic Derivatives of an AUV Based on the Water Tunnel Testing Maneuvers

Coefficients or hydrodynamic derivatives of autonomous underwater vehicles play a key role in their development. The most popular way for the estimation of coefficient is to implement captive model tests such as straight line tests and planar motion mechanism tests in towing tanks. In this paper, investigation of hydrodynamic derivatives was performed based on the water tunnel maneuvers. Forces...

A Theoretical Approach to Facilitating Transition Phase Motion in a Positively Buoyant Autonomous Underwater Vehicle

Positively buoyant autonomous underwater vehicles (AUVs) operate at survey speeds with a pitch angle that is maintained through application of the control surfaces, sufficient to generate hydrodynamic forces to counteract the excess buoyancy. To facilitate lower forward speeds and the ability to hover requires some additional method of control. This paper reviews possible options and then indic...

Investigation on Nose and Tail Shape Effects on Hydrodynamic Parameters in Autonomous Underwater Vehicles

Development of autonomous underwater vehicles (AUVs) which meets the design constraints and provides the best hydrodynamic performance is really an important challenge in the field of hydrodynamics. In this paper a new profile is used for designing the hull of AUVs. The nose and tail profiles of an AUV using presented profile is designed such that it can properly consider the length constraints...

Adaptive Robust Control for Trajectory Tracking of Autonomous underwater Vehicles on Horizontal Plane

This manuscript addresses trajectory tracking problem of autonomous underwater vehicles (AUVs) on the horizontal plane. Adaptive sliding mode control is employed in order to achieve a robust behavior against some uncertainty and ocean current disturbances, assuming that disturbance and its derivative are bounded by unknown boundary levels. The proposed approach is based on a dual layer adaptive...
