Book Large Space Structures Dynamics and Control

Download or read book Large Space Structures Dynamics and Control written by S.N. Atluri and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 367 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph is intended to provide a snapshot of the status and opportunities for advan cement in the technologies of dynamics and control oflarge flexible spacecraft structures. It is a reflection ofthe serious dialog and assessments going on all over the world,across a wide variety of scientific and technical disciplines, as we contemplate the next major milestone in mankind's romance with space: the transition from exploration and experimentation to commercial and defense exploitation. This exploitation is already in full swing in the space communications area. Both military and civilian objectives are being pursued with increasingly more sophisticated systems such as large antenna reflectors with active shape control. Both the NATO and Warsaw pact alliances are pursuing permanent space stations in orbit: large structural systems whose development calls for in-situ fabrication and/or assembly and whose operation will demand innovations in controls technology. The last ten years have witnessed a fairly brisk research activity in the dynamics and control oflarge space structures in orderto establish a technology base forthe development of advanced spacecraft systems envisioned for the future. They have spanned a wide spectrum of activity from fundamental methods development to systems concept studies and laboratory experimentation and demonstrations. Some flight experiments have also been conducted for various purposes such as the characterization of the space enviroment, durability of materials and devices in that environment, assembly and repair operations, and the dynamic behavior of flexible structures. It is this last area that has prompted this monogram.

Book Adaptive Techniques for Control of Large Space Structures

Download or read book Adaptive Techniques for Control of Large Space Structures written by R. L. Kosut and published by . This book was released on 1984 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report is a collection of published papers reporting on research supported by AFOSR. These papers deal primarily with theoretical aspects of adaptive control of systems which cannot be precisely modeled, e.g., unmodeled dynamics and disturbances. These latter characteristics are fundamental issues in adaptive (and nonadaptive) control design for large space structures (LSS). Some of the general topics covered include: LSS modeling and model error, decentralized control, robust adaptive control, global stability, local stability, and persistent excitation. Keywords include: Large space structures; adaptive control; robust control; equations.

Book Modeling Analysis and Optimization Issues for Large Space Structures

Download or read book Modeling Analysis and Optimization Issues for Large Space Structures written by and published by . This book was released on 1983 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document contains the proceedings of the Air Force/NASA Workshop on Modeling, Analysis, and Optimization Issues for Large Space Structures held in Williamsburg, Virginia, May 13-14 1982. The theme of the workshop was modeling, analysis, and optimization of large space structures, including structure control interaction. Speakers were drawn primarily from industry, with participation from universities and government. The workshop was organized into three sessions: mathematical modeling, analysis methodology, and optimization for controllability. Results of the workshop were discussed in a final session. The workshop presentations ranged over many topics in large space structures, including structure-control interaction, structural and structural dynamics modeling, thermal analysis, testing, design, and optimization. The interdisciplinary area of structure-control interaction, which is a challenge to analysts, designers, and test engineers, was clearly emphasized. Not addressed in the workshop was the important subject of structural deployment.

Book Adaptive Control Techniques for Large Space Structures

Download or read book Adaptive Control Techniques for Large Space Structures written by robert L. Kosut and published by . This book was released on 1987 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes the research performed on adaptive control techniques for Large Space Structures (LSS). The research effort concentrated on two areas: (1) on-line robust design from identified models - what is referred to here as adaptive calibration; and (2) an analysis of slow-adaptation for adaptive control of LSS. The report summarizes the results obtained in theses areas and also includes Appendices which contain technical articles: (1) Adaptive Control of Large Space Structures; (2) Adaptive Control Via Finite Modeling and Robust Control; (3) On the use of the Method of Averaging for the Stability analysis of Adaptive Linear Control Systems; and (4) Conditions for the Convergence and Divergence of Parameter Adaptive Linear Systems.

Book Modeling and Control of Large Flexible Vehicles in the Atmosphere and Space

Download or read book Modeling and Control of Large Flexible Vehicles in the Atmosphere and Space written by and published by . This book was released on 1987 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: Summary of major research findings in three topical areas: 1) traveling wave concepts in the dynamics and control of Large Space Structures, 2) passive damping in Large Space Structures Applications, and 3) active control of rigid and flexible Manipulator Arms. The traveling wave concepts for characterizing the dynamics of flexible structures have introduced an alternative to modal synthesis and established a basis for the development of new controls algorithms. Passive damping studies identified various types of damping mechanisms including thermoelastic, and electromagnetic, and quantified their relative contributions. The active control studies generated a number of algorithms and control strategies and demonstration applications.

Book Computational Methods and Software Systems for Dynamics and Control of Large Space Structures

Download or read book Computational Methods and Software Systems for Dynamics and Control of Large Space Structures written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-07-23 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two key areas of crucial importance to the computer-based simulation of large space structures are discussed. The first area involves multibody dynamics (MBD) of flexible space structures, with applications directed to deployment, construction, and maneuvering. The second area deals with advanced software systems, with emphasis on parallel processing. The latest research thrust in the second area involves massively parallel computers. Park, K.
