Download or read book Real Time Implementation of an Adaptive Depth Controller for a Submersible written by James M. Williams and published by . This book was released on 1989 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: An Autonomous Underwater Vehicle (AUV) is an unmanned submersible vehicle capable of performing a variety of missions. The AUV, which is the subject of this research, is a small prototype vehicle equipped with various control surfaces as well as telemetry devices which provide pertinent measurements of the vehicle states. This research is directed toward the development and implementation of a digital-control program which provides robust depth control of the vehicle. An adaptive parameter estimation routine is used to develop the model of the relationship between the actuator commands and vehicle response. State feedback is then provided using a variable-structure approach. The control algorithm has been implemented through a Turbo Pascal digital-control program executed on a PC/AT computer. Results of the parameter estimation routine and controller implementation are discussed. Keywords: Theses; Analog simulation; Experimental data. (kr).

Download or read book Real Time Adaptive Control of an Autonomous Underwater Vehicle AUV written by Michael H. Davis and published by . This book was released on 1989 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this research the problem of designing a controller for the dive maneuver of an Autonomous Underwater Vehicle (AUV) is addressed. The highly nonlinear nature of the vehicle dynamics and the requirement for the fast maneuvering call for robust control techniques. In particular Variable Structure Control (VSC) combined with Adaptive Control (AC) techniques seem to yield satisfactory performance in terms of robustness, capability to adjust to different operating conditions, and speed of response. Also linear robust techniques based on LQG and robust observers are presented to address the case when the whole state (in terms of pitch rate, pitch, and depth) is not available for measurement.

Download or read book Real time Coastal Observing Systems for Marine Ecosystem Dynamics and Harmful Algal Blooms written by Babin, Marcel and published by UNESCO. This book was released on 2008-06-05 with total page 880 pages. Available in PDF, EPUB and Kindle. Book excerpt: The proliferation of harmful phytoplankton in marine ecosystems can cause massive fish kills, contaminate seafood with toxins, impact local and regional economies and dramatically affect ecological balance. Real-time observations are essential for effective short-term operational forecasting, but observation and modelling systems are still being developed. This volume provides guidance for developing real-time and near real-time sensing systems for observing and predicting plankton dynamics, including harmful algal blooms, in coastal waters. The underlying theory is explained and current trends in research and monitoring are discussed.Topics covered include: coastal ecosystems and dynamics of harmful algal blooms; theory and practical applications of in situ and remotely sensed optical detection of microalgal distributions and composition; theory and practical applications of in situ biological and chemical sensors for targeted species and toxin detection; integrated observing systems and platforms for detection; diagnostic and predictive modelling of ecosystems and harmful algal blooms, including data assimilation techniques; observational needs for the public and government; and future directions for research and operations.

This book was released on 1996-12-03 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: The United States faces decisions requiring information about the oceans in vastly expanded scales of time and space and from oceanic sectors not accessible with the suite of tools now used by scientists and engineers. Advances in guidance and control, communications, sensors, and other technologies for undersea vehicles can provide an opportunity to understand the oceans' influence on the energy and chemical balance that sustains humankind and to manage and deliver resources from and beneath the sea. This book assesses the state of undersea vehicle technology and opportunities for vehicle applications in science and industry. It provides guidance about vehicle subsystem development priorities and describes how national research can be focused most effectively.
