Available in PDF, EPUB and Kindle. Book excerpt: Autonomous underwater vehicles (AUVs) are emerging as a promising solution to help us explore and understand the ocean. The global market for AUVs is predicted to grow from 638 million dollars in 2020 to 1,638 million dollars by 2025 – a compound annual growth rate of 20.8 percent. To make AUVs suitable for a wider range of application-specific missions, it is necessary to deploy multiple AUVs to cooperatively perform the localization, tracking and formation tasks. However, weak underwater acoustic communication and the model uncertainty of AUVs make achieving this challenging. This book presents cutting-edge results regarding localization, tracking and formation for AUVs, highlighting the latest research on commonly encountered AUV systems. It also showcases several joint localization and tracking solutions for AUVs. Lastly, it discusses future research directions and provides guidance on the design of future localization, tracking and formation schemes for AUVs. Representing a substantial contribution to nonlinear system theory, robotic control theory, and underwater acoustic communication system, this book will appeal to university researchers, scientists, engineers, and graduate students in control theory and control engineering who wish to learn about the core principles, methods, algorithms, and applications of AUVs. Moreover, the practical localization, tracking and formation schemes presented provide guidance on exploring the ocean. The book is intended for those with an understanding of nonlinear system theory, robotic control theory, and underwater acoustic communication systems.

This book was released on 2020 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: Autonomous underwater vehicles hold great potential in the realms of industry, military, scientific, and personal usage. The applications of intelligently applied autonomous functionality could improve work performed on subsea infrastructure, commercial shipping lane maintenance, canal and channel observation, search and rescue, military applications, as well as general scientific research. Given such potential, and supposing that existing technological barriers to progress could be overcome, what could a potential system architecture of future autonomous underwater vehicles look like? Fundamentally this thesis asks: “could novel architectures of AUV systems – specifically pairing AUVs to remote service platforms – lead to significant performance increases?” In approaching this subject, a specific case study is leveraged where autonomous underwater vehicles were extensively used: the search for Malaysian Air flight 370. This specific mission profile has been extensively documented by others laying a comprehensive framework. It represents the single largest search and rescue operation ever performed. Within this thesis, whole-system performance metrics of this search and rescue operation are compared against calculated performance metrics of systematically generated possible architectures. In decomposing the system into its functional elements, a deterministic evaluation is executed followed by a probabilistic examination of the system as modeled. The results of the probabilistic model are also interpreted via a Pareto ranking methodology where Pareto surfaces are identified in multidimensional tradespaces. These component cases which comprise the Pareto surface are subsequently removed from the dataset, and the process is run again. This iterative approach demonstrated that the top ten performing architectures were comprised entirely out of architectures with either one or four AUVs. The outputs of these models are subsequently compared against the baseline system used in the search for MH370. Following the analysis, a major fault was identified in the foundations of all of the models surrounding a figure of merit wherein the time to the seafloor was calculated for all architectures. All of the top ten performing design vectors – systems which contained one or four AUVs – were unchanged due to this error. Architectures which were affected by this error -- systems with more than four AUVs -- were impacted negatively. Several methods of re-imagining the error are presented herein as complexities that are inherent in the system, which are not handled by these models. These new emergent complexities were present in the system prior to the model construction, but unaccounted for. Discovery of this faulty assumption laid bare several architectural decisions which are unexplored in this thesis, but could provide the foundation for future work in this space. The outcome of these modeling efforts suggests that pairing an autonomous underwater vehicle with an autonomous service platform can result in increases in all performance metrics. Specific metrics which are improved include daily search area rate, calendar mission completion time, and total project cost. This improvement is specifically calibrated to the case study of MH370, but the performance metrics themselves are not exclusively applicable to search and rescue operations. This model indicates that such a system could accomplish the same mission in less time for half the cost. This thesis presents a vision of future autonomous underwater vehicle systems in which daily operational time, search area rates, calendar mission completion times, and total system costs can all be improved relative to the existing standards. Such improvements are equally applicable to commercial, industrial, military, civilian, and scientific endeavors in which autonomous underwater vehicles could be a potential tool.

Download or read book Tracking Control for a Formation of Autonomous Underwater Vehicles written by John Gornowich and published by . This book was released on 2010 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Autonomous Underwater Vehicles (AUVs) are being implemented for a multitude of military and commercial applications, as well as scientific research and surveying. Because of the environment that these vehicles are tasked to perform duties in, there is a need for guidance and control schemes that are precise, yet robust. There are still major research efforts underway in the areas of system identification, modeling, control, and optimization to enhance the autonomy of these vehicles. This will allow for more advanced control schemes while maintaining the robustness that is required to operate in a diverse and hazardous environment such as the ocean. Previous control algorithms for commercially available AUVs have been generally restricted to tracking straight-line trajectories between predetermined waypoints. These vehicles will typically employ an additional control technique that allows for obstacle determination and avoidance. Again, this is generally limited to a simple line of sight detection and preprogrammed avoidance maneuver. An even less abundant and mature group of control schemes is available for a cooperative technique by a group of AUVs to accomplish a common goal. This thesis addresses the development of a robust suboptimal tracking control algorithm that will efficiently and effectively track an identifiable target while maintaining a formation with cooperating vehicles. This work will examine the possibility of utilizing a common LTI control scheme for maneuvering the actual nonlinear vehicle model. It will also investigate a simple heuristic approach to determining how to track a given target, as well as in what formation to maintain the group structure.

Download or read book Development and Testing of Navigation Algorithms for Autonomous Underwater Vehicles written by Francesco Fanelli and published by Springer. This book was released on 2019-04-16 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on pose estimation algorithms for Autonomous Underwater Vehicles (AUVs). After introducing readers to the state of the art, it describes a joint endeavor involving attitude and position estimation, and details the development of a nonlinear attitude observer that employs inertial and magnetic field data and is suitable for underwater use. In turn, it shows how the estimated attitude constitutes an essential type of input for UKF-based position estimators that combine position, depth, and velocity measurements. The book discusses the possibility of including real-time estimates of sea currents in the developed estimators, and highlights simulations that combine real-world navigation data and experimental test campaigns to evaluate the performance of the resulting solutions. In addition to proposing novel algorithms for estimating the attitudes and positions of AUVs using low-cost sensors and taking into account magnetic disturbances and ocean currents, the book provides readers with extensive information and a source of inspiration for the further development and testing of navigation algorithms for AUVs.
