Navigation of a Biomimetic Autonomous Underwater Vehicle by Using Monocular Vision in a Known Environment

Author: Yang ShiPublisher: Springer Nature
ISBN: 3031193547
Category : Technology & Engineering
Languages : en
Pages : 210
Book Description
This book provides a comprehensive overview of marine control system design related to underwater robotics applications. In particular, it presents novel optimization-based model predictive control strategies to solve control problems appearing in autonomous underwater vehicle applications. These novel approaches bring unique features, such as constraint handling, prioritization between multiple design objectives, optimal control performance, and robustness against disturbances and uncertainties, into the control system design. They therefore form a more general framework to design marine control systems and can be widely applied. Advanced Model Predictive Control for Autonomous Marine Vehicles balances theoretical rigor – providing thorough analysis and developing provably-correct design conditions – and application perspectives – addressing practical system constraints and implementation issues. Starting with a fixed-point positioning problem for a single vehicle and progressing to the trajectory-tracking and path-following problem of the vehicle, and then to the coordination control of a large-scale multi-robot team, this book addresses the motion control problems, increasing their level of challenge step-by-step. At each step, related subproblems such as path planning, thrust allocation, collision avoidance, and time constraints for real-time implementation are also discussed with solutions. In each chapter of this book, compact and illustrative examples are provided to demonstrate the design and implementation procedures. As a result, this book is useful for both theoretical study and practical engineering design, and the tools provided in the book are readily applicable for real-world implementation.

Book Description
Underwater vehicles often use acoustics or dead reckoning for global positioning, which is impractical for low cost, high proximity applications. An optical based positional feedback system for a wave tank operated biomimetic station-keeping vehicle was made using an extended Kalman filter and a model of a nearby light source. After physical light model verification, the filter estimated surge, sway, and heading with 6 irradiance sensors and a low cost inertial measurement unit (~$15). Physical testing with video feedback suggests an average error of ~2cm in surge and sway, and ~3deg in yaw, over a 1200 cm2 operational area. This is 2-3 times better, and more consistent, than adaptations of prior art tested alongside the extended Kalman filter feedback system. The physical performance of the biomimetic platform was also tested. It has a repeatable forward velocity response with a max of 0.3 m/s and fair stability in surface testing conditions.

Book Description
(Cont.) The performance of the vehicle as reported in this thesis compare well to the previously recorded performance measurements and to theoretical estimates based on the capabilities of the actuators. However, measurements of performance would benefit greatly from better control during testing and from a larger testing space. Developing a more effective means of sway actuation would also benefit the vehicle's performance.
Biomimetic Improvement of the Maneuvering Qualities of Unmanned Underwater Vehicles

Book Description
In recent years, biomimetics has been used as a source of inspiration to improve the performance of engineered systems in several disciplines. In this thesis, we emulate the function of the retractable dorsal fins in tunas to improve the maneuvering performance of a typical autonomous underwater vehicle, the REMUS 100 AUV. We are introducing dorsal-like fins on the AUV that can be erected to alter its maneuvering hydrodynamic coefficients, and hence affect the transient and steady-state turning response. In order to study systematically the effect of adding dorsal fins, we built a six degrees of freedom simulation model of the REMUS AUV. The model included body and rudder lift forces and moments, added mass forces and moments, gyroscopic and centrifugal forces, drag forces and moments, and body forces and moments such as buoyancy and gravity terms. To target the horizontal plane maneuvering characteristics, we reduced the model to a 3 DOF simulation, allowing the dorsal fin to vary in area, location along the length of the AUV, as well as having a turning angle with respect to the REMUS x-axis. We find that the addition of the fin can improve the performance, as measured by the radius of turning and rate of turning, moderately only when placed ahead of the center of gravity. However, when the dorsal fin is also allowed to rotate in the opposite direction that the rudder, substantial improvement in maneuvering performance is noted, increasing the turning rate up to 25%.
