Software Adaptation for an Unmanned Undersea Vehicle [PDF]

IEEE Software, 2019
Most current software systems are not adaptable, making them less capable of achieving their objectives. We are developing a method to optimize software for new environments automatically. An independent evaluation has demonstrated that this method adapts to degraded sensors, changing environmental conditions, and a loss of power.

Conceptual Design of Future Undersea Unmanned Vehicle (UUV) System for Mine Disposal [PDF]

IEEE Systems Journal, 2014
A conceptual design is proposed for an effective mine countermeasure (MCM) system, which consists of three unmanned underwater vehicles (UUVs) and 10-20 small charged deliverable vehicles. New underwater optical communication systems are introduced to improve onboard mine reconnaissance and decision making with the key technologies focused on system ...

Unmanned Surface And Undersea Vehicles: Capabilities And Potential [PDF]

International conference KNOWLEDGE-BASED ORGANIZATION, 2015
Abstract This paper proposes a new technological solution for the sea observation using an Unmanned Surface Vehicle (USV) or Unmanned Undersea Vehicles (UUV). The term USV refers to any vehicle that operates on the surface of the water without a crew.

UNDERSEA: An Exemplar for Engineering Self-Adaptive Unmanned Underwater Vehicles [PDF]

2017 IEEE/ACM 12th International Symposium on Software Engineering for Adaptive and Self-Managing Systems (SEAMS), 2017
Recent advances in embedded systems and underwater communications raised the autonomy levels in unmanned underwater vehicles (UUVs) from human-driven and scripted to adaptive and self-managing. UUVs can execute longer and more challenging missions, and include functionality that enables adaptation to unexpected oceanic or vehicle changes.

Bottom-Following Control of Underactuated Unmanned Undersea Vehicles With Input Saturation [PDF]

IEEE Access, 2020
This article addresses the subject for bottom-following control of underactuated unmanned undersea vehicles (UUVs) with input saturation in the presence of unknown model uncertainties and unknown external disturbances. A robust adaptive dynamic surface bottom-following control scheme is developed based on the recursive sliding mode with nonlinear gains

Obstacle Avoidance for Unmanned Undersea Vehicle in Unknown Unstructured Environment [PDF]

Mathematical Problems in Engineering, 2013
To avoid obstacle in the unknown environment for unmanned undersea vehicle (UUV), an obstacle avoiding system based on improved vector field histogram (VFH) is designed. Forward looking sonar is used to detect the environment, and the divisional sonar modal is applied to deal with the measure uncertainty.

A Concept of Nuclear Reactor Power for Unmanned Undersea Vehicle

水下无人系统学报, 2022
High-speed long-range unmanned undersea vehicles can expand various new combat modes. However, the power system is one of its bottlenecks. Nuclear power is an effective solution to address this problem. The miniaturization of the nuclear reactor power system is technically difficult.

Output Feedback Spatial Trajectory Tracking Control of Underactuated Unmanned Undersea Vehicles [PDF]

IEEE Access, 2020
In this paper, suffering from both parameter perturbation and unknown ocean currents, the spatial trajectory tracking problem of an underactuated unmanned undersea vehicle (UUV) is investigated in the absence of full state information. The equivalent output injection sliding mode observer is applied to estimate the linear and angular velocities of ...

Enabling Under Ice Glider Operations: A Backseat Driver Approach

Journal of Field Robotics, Volume 43, Issue 5, Page 3292-3311, August 2026.
ABSTRACT Polar Oceans are key locations for forcing global ocean circulation, influencing both global climate and biogeochemical cycles. Due to restricted access to these seasonally and perennially ice‐covered regions, these areas are severely undersampled.
