Time-Delay Controller Design for Position Control of Autonomous Underwater Vehicle Under Disturbances
TL;DR: An integral sliding-mode controller to be supplemented to the conventional TDC to improve the control precision even if the DVL navigation system is in operation and is computationally simple and robust to unmodeled dynamics and disturbances.

Second-order sliding-mode controller for autonomous underwater vehicle in the presence of unknown disturbances
TL;DR: In this article, a second-order sliding-mode controller (2-SMC) is proposed to stabilize an AUV in the presence of unknown hydrodynamics and unknown disturbances.

Development of hovering type AUV “Cyclops” and its performance evaluation using image mosaicing
TL;DR: In this paper, a hovering-type autonomous underwater vehicle called Cyclops is introduced, which utilizes a lawnmower trajectory without changing its heading direction to obtain source images with homogeneous optical characteristics for underwater image mosaicing.

Acoustic beam profile-based rapid underwater object detection for an imaging sonar
TL;DR: In this article, the authors proposed a method to provide an automatic detection alarm indicating the presence of suspected underwater objects using high-speed imaging sonar, which is based on the cross-correlations between two successive acoustic beam profiles of imaging sonars.

Development of a flap-type mooring-less wave energy harvesting system for sensor buoy
TL;DR: To reduce deployment and maintenance costs, a novel wave energy converter (WEC) is proposed for mooring-less sensor buoys in this article, which is based on a small size WEC capable of harvesting wave energy without moorings, which can reduce the installation cost.
