Robust Position Control of an Over-actuated Underwater Vehicle under Model Uncertainties and Ocean Current Effects Using Dynamic Sliding Mode Surface and Optimal Allocation Control

Sensors, 2021
Underwater vehicles (UVs) are subjected to various environmental disturbances due to ocean currents, propulsion systems, and un-modeled disturbances. In practice, it is very challenging to design a control system to maintain UVs stayed at the desired ...

Extensible Control Architecture for Over-Actuated Vehicles [PDF]

2019 19th International Conference on Control, Automation and Systems (ICCAS), 2019
Most of today's passenger cars are over-actuated. This over-actuation is expected to grow going towards self-driving cars. However, the necessary systems that would be needed for a safe and a comfortable autonomous driving remain uncertain. This paper aims to provide an extensible control architecture that does not depend on a particular system ...

Station-Keeping Control of a Hovering Over-Actuated Autonomous Underwater Vehicle Under Ocean Current Effects and Model Uncertainties in Horizontal Plane

IEEE Access, 2021
Nowadays, underwater vehicles (UVs) are applied to various tasks such as carrying objects or maintenance of underwater structures. To carry out well these tasks, UVs should keep the position and orientation in the water to perform the specified tasks ...

Maneuvering of an over-actuated autonomous underwater vehicle using both through-body tunnel thrusters and control surfaces

, 2011
The maneuvering performance of an over-actuated AUV (2m long, 254mm diameter) has been tested operating on the free surface (97% displacement submerged). Straight line speed tests and turning circle tests have been performed.

Grid-based GA path planning with improved cost function for an over-actuated hover-capable AUV [PDF]

, 2014
For an AUV to perform a long-range mission with its maximum endurance, its energy consumption during transit must be kept to a minimum. This paper presents an improved cost function for a grid-based genetic algorithm (GA) path planning in 2D static ...
