This book was released on 2016 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Small scale unmanned underwater vehicles provide an opportunity to safely and efficiently complete tasks such as boat hull inspection and subsea development survey. These Remotely Operated Vehicles (ROVs) can be made more efficient if navigating underwater autonomously. This requires the development of highly accurate navigation and control algorithms, which, in turn, require a high-fidelity dynamic model of the vehicle based on first principles and validated by empirical data. In this thesis, a simulation of a dynamics model for a commercially available ROV is developed. Empirical data from open-loop testing is used to generate a second-order transfer function using system identification to validate the simulation model. The transient response characteristics of the experimentally generated transfer function are then utilized to fine-tune the physical parameters in the simulation model. Finally, autopilot systems are designed using classical control theory to enable autonomous control over the attitudes and depth of the underwater vehicle.

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 Advanced Model Predictive Control for Autonomous Marine Vehicles written by Yang Shi and published by Springer Nature. This book was released on 2023-02-13 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
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).

Download or read book Contribution to the Model and Navigation Control of an Autonomous Underwater Vehicle written by Julián González Agudelo and published by . This book was released on 2015 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis deals with the further development of an existing underwater vehicle for autonomous navigation. The vehicle was conceived to navigate over the sea surface and, at certain fixed points, to dive vertically in order to obtain a profile of a water column. The main objectives of the thesis are the improvement of the hardware and software of the vehicle in order to make it fully operational, and the design and implementation of control techniques for autonomous navigation. The problem of autonomous navigation is addressed first with the calculation of an hydrodynamic model in 3DoF. An extensive study about the selection of the coefficients is performed, using a linearized model. The calculation of the coefficients is done using two approaches: a geometric one and another one based on least squares techniques applied to experimental data obtained during sea trials. The least squares method gives satisfactory results and the simulations fits the experimental data. The resulting hydrodynamic model is completed with the physical constraints of the actuators of the vehicle. Solving the autonomous navigation problem requires the design of controllers for both the inner loop (dynamic) and the outer loop (kinematic). Several solutions based on type-1 TSK fuzzy control are presented for velocity control, yaw control, pure pursuit navigation, and path following. The fuzzy controller is used to manage different linear controllers designed for specific conditions. The hydrodynamic model plays an important role in the design of the controller for the inner loop. In addition, a gain scheduled controller is designed to validate a particular case of the fuzzy controller in the inner loop. Regarding the finishing of the vehicle to be fully operational, the improvements begin with a new driver for the lateral thrusters because they lacked backwards movement capability. Additionally, upgrades in the handling of the vehicle had to devised. In this respect, a wireless on/off system is presented to power the vehicle, and a WiFi connection is adapted to manipulate the software of the vehicle remotely. Furthermore, a study of the currents and power of the immersion system in order to reduce the power consumption is performed, and the hardware is improved with the inclusion of some commercial devices, like an IMU, CTD, and acoustic localization system. The software is improved in several aspects. First, some problems derived from previous works are debugged. The system is then restructured with a multithread development, which provides robustness and modularity. As the system needed an extension of the protocol communication for easy handling, a robust protocol communication is implemented with the possibility to execute scripts. Finally, the existing graphical user interface is simplified in order to provide only the information required by the operator. In order to improve the buoyancy of the vehicle, several foams are designed, adjusted to the geometry of the vehicle, and a ballast system is also included for fine adjustment. Finally, several tests in the laboratory, a swimming pool, a channel, and at sea are performed in order to check the performance of the vehicle. Results show a correct behavior of hardware and software, and also validate the performance of the controllers designed for autonomous navigation.
