Book excerpt: The development and testing of Autonomous Underwater Vehicle (AUV) hardware and software is greatly complicated by vehicle inaccessibility during operation. Integrated simulation remotely links vehicle components and support equipment with graphics simulation workstations, allowing complete real-time, pre-mission, pseudo-mission and post-mission visualization and analysis in the lab environment. Integrated simulator testing of software and hardware is a broad and versatile method that supports rapid and robust diagnosis and correction of system faults. This method is demonstrated using the Naval Postgraduate School (NPS) AUV. High-resolution three-dimensional graphics workstations can provide real-time representations of vehicle dynamics, control system behavior, mission execution, sensor processing and object classification. Integrated simulation is also useful for development of the variety of sophisticated artificial intelligence applications needed by an AUV. Examples include sonar classification using an expert system and path planning using a circle world model. The flexibility and versatility provided by this approach enables visualization and analysis of all aspects of AUV development. Integrated simulator networking is recommended as a fundamental requirement for AUV research and deployment.

Download or read book Autonomous Underwater Vehicles written by Sabiha Wadoo and published by CRC Press. This book was released on 2017-12-19 with total page 165 pages. Available in PDF, EPUB and Kindle. Book excerpt: Underwater vehicles present some difficult and very particular control system design problems. These are often the result of nonlinear dynamics and uncertain models, as well as the presence of sometimes unforeseeable environmental disturbances that are difficult to measure or estimate. Autonomous Underwater Vehicles: Modeling, Control Design, and Simulation outlines a novel approach to help readers develop models to simulate feedback controllers for motion planning and design. The book combines useful information on both kinematic and dynamic nonlinear feedback control models, providing simulation results and other essential information, giving readers a truly unique and all-encompassing new perspective on design. Includes MATLAB® Simulations to Illustrate Concepts and Enhance Understanding Starting with an introductory overview, the book offers examples of underwater vehicle construction, exploring kinematic fundamentals, problem formulation, and controllability, among other key topics. Particularly valuable to researchers is the book’s detailed coverage of mathematical analysis as it applies to controllability, motion planning, feedback, modeling, and other concepts involved in nonlinear control design. Throughout, the authors reinforce the implicit goal in underwater vehicle design—to stabilize and make the vehicle follow a trajectory precisely. Fundamentally nonlinear in nature, the dynamics of AUVs present a difficult control system design problem which cannot be easily accommodated by traditional linear design methodologies. The results presented here can be extended to obtain advanced control strategies and design schemes not only for autonomous underwater vehicles but also for other similar problems in the area of nonlinear control.

Download or read book A Study of 3 D Visualization and Knowledge Based Mission Planning and Control for the NPS Model 2 Autonomous Underwater Vehicle written by Ray Charles Rogers and published by . This book was released on 1989 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Specific tasking/total military mission concepts for subsea tasks have been developed that demand substantially more endurance and range than can be provided by manned submersibles and remotely operated vehicles, respectively. Small autonomous unmanned systems can provide the best combination of speed, endurance, range, depth capacity, and flexibility needed to make these concepts realizable. As the U.S. military has continued to identify more and more tasks that can be performed by autonomous systems, the NPG has heightened its research efforts to develop an experimental autonomous underwater vehicle (AUV) to address these requirements. A series of NPS AUV simulation systems have been developed that couple knowledge-based mission planning and control systems with 3-D visualization (graphics) workstations that communicate across an interprocess communications network. Development of these simulation systems have produced an extremely useful 'laboratory environment' for rapid prototyping of AUV planning, navigation, and control subsystems software. This thesis updates and extends the formats of functionality of the simulation systems to include a Mission Planning and Control Workstation as a prototype for use aboard AUV deployment vessels, upgrades mission profiles, and incorporates improvements to the software interface between the mission planning and control subsystem and the 3-D visualization subsystem. Keywords: Three dimensional display systems; Interactive graphics; Theses.(edc).

Book excerpt: "Underwater Vehicles: Design and Applications first explores the application of the adaptive Kalman filter algorithm to the estimation of high speed autonomous underwater vehicle dynamics. The authors investigate the performances of different control schemes, from non-model-based to model-based and adaptive model-based, implemented on a low-inertia underwater vehicle for three-dimensional helical trajectory tracking. Control laws for collision avoidance in three-dimensional environments are introduced, considering scenarios where a vehicle detects arbitrarily shaped and nonconvex obstacles using sensors"--
Download or read book A Virtual World for an Autonomous Underwater Vehicle written by Donald P. Brutzman and published by . This book was released on 1994 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: A critical bottleneck exists in Autonomous Underwater Vehicles (AUV) design and development. It is tremendously difficult to observe, communicate with and test underwater robots, because they operate in a remote and hazardous environment where physical dynamics and sensing modalities are counter intuitive. An underwater virtual world can comprehensively model all salient functional characteristics of the real world in real time. This virtual world is designed from the perspective of the robot, enabling realistic AUV evaluation and testing in the laboratory. Three-Dimensional real-time computer graphics are our window into that virtual world. Visualization of robot interactions within a virtual world permits sophisticated analyses of robot performance that are otherwise unavailable. Sonar visualization permits researchers to accurately 'look over the robot's shoulder' or even 'see through the robot's eyes' to intuitively understand sensor-environment interactions. Extending the theoretical derivation of a set of six-degree-of-freedom hydrodynamics equations has provided a fully general physics-based model capable of producing highly non-linear yet experimentally-verifiable response in real time. Distribution of underwater virtual world components enables scalability and real-time response. The IEEE Distributed Interactive Simulation (DIS) protocol is used for compatible live interaction with other virtual worlds. Network connections allow remote access, demonstrated via Multicast Backbone (MBone) audio and video collaboration with researchers at remote locations. Integrating the World-Wide Web allows rapid access to resources distributed across the Internet.

This book was released on 2012-12-06 with total page 421 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 34 (thesis year 1989) a total of 13,377 theses titles from 26 Canadian and 184 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 34 reports theses submitted in 1989, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.
