Available in PDF, EPUB and Kindle. Book excerpt: Robotic technology offers two potential benefits for future space exploration. One benefit is minimizing the risk that astronauts face. The other benefit is increasing their productivity. Realizing the benefits of robotic technology in space will require solving several problems which are unique and now becoming active research topics. One of the most important research areas is dynamics, control, motion and planning for space robots by considering the dynamic interaction between the robot and the base (space station, space shuttle, or satellite). Any inefficiency in the planning and control can considerably risk by success of the space mission. Space Robotics: Dynamics and Control presents a collection of papers concerning fundamental problems in dynamics and control of space robots, focussing on issues relevant to dynamic base/robot interaction. The authors are all pioneers in theoretical analysis and experimental systems development of space robot technology. The chapters are organized within three problem areas: dynamics problems, nonholonomic nature problems, and control problems. This collection provides a solid reference for researchers in robotics, mechanics, control, and astronautical science.

This book was released on 2012-12-06 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many mechanical systems are actively controlled in order to improve their dynamic performance. Examples are elastic satellites, active vehicle suspension systems, robots, magnetic bearings, automatic machine tools. Problems that are typical for mechanical systems arise in the following areas: - Modeling the mechanical system in such a way that the model is suitable for control design - Designing multivariable controls to be robust with respect to parameter variations and uncertainties in system order of elastic structures - Fast real-time signal processing - Generating high dynamic control forces and providing the necessary control power - Reliability and safety concepts, taking into account the growing role of software within the system The objective of the Symposium has been to present methods that contribute to the solutions of such problems. Typical examples are demonstrating the state of the art It intends to evalua~ the limits of performance that can be achieved by controlling the dynamics, and it should point to gaps in present research and areas for future research. Mainly, it has brought together leading experts from quite different areas presenting their points of view.

Download or read book Parasitic Phenomena in the Dynamics of Industrial Devices written by Alberto Borboni and published by CRC Press. This book was released on 2011-10-06 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the real world the dynamic behavior of a real machine presents either unforeseen or limiting phenomena: both are undesired, and can be therefore be classified as parasitic phenomena — unwanted, unforeseen, or limiting behaviors. Parasitic Phenomena in the Dynamics of Industrial Devices describes the potential causes and effects of these behaviors and provides indications that could minimize their influence on the mechanical system in question. The authors introduce the phenomena and explore them through real cases, avoiding academic introductions, but inserting the entire academic and experimental knowledge that is useful to understand and solve real-world problems. They then examine these parasitic phenomena in the machine dynamics, using two cases that cover the classical cultural division between cam devices and mechanisms. They also present concrete cases with an amount of experimental data higher than the proposed ones and with a modern approach that can be applied to various mechanical devices, acquiring real knowledge superior to one of the mere finite element systems or collections of mechanical devices. Organizes machine dynamics through systems theory to give a comprehensive vision of the design problem Details machine dynamics at an advanced mathematics level and avoids redundancy of fundamental knowledge Introduces real machine cases for solutions to practical problems Covers two broad classes of mechanical devices that are widely used in the construction of instrumental goods Employs a mechatronic approach that can be applied to electro-mechanical, hydro-mechanical, or pneumo-mechanical machines Highlighting industrial devices in the manufacturing industry, including industrial indexing devices and industrial robots, the book offers case studies, advanced models, design methods, and short examples of applications. It is of critical importance for any manufacturing enterprise that produces significant amounts of objects through a process with one or more automated phases.

Download or read book Vibration Reduction for Flexible Structures by Smoothing Commands written by Jie Huang and published by Lulu.com. This book was released on 2020-01-04 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book described vibration reduction for flexible structures by the command smoothing techniques. The Command smoothing technique is a kind of open-loop controller. The operator's commands filter through a piecewise continuous function, called smoother, to produce smoothed commands. Smoothed commands move flexible dynamic systems toward desired positions with minimal oscillations. Five types of command smoother were reported including one-piece, two-pieces, three-pieces, and four-pieces smoothers, and the smoother for multi-mode Duffing oscillators. All smoothers are robust to changes in the system parameters and working conditions. The command smoothing technique has been successfully applied to industrial cranes, sloshing suppression, flexible manipulators, high-speed cam and follower systems, and helicopter slung loads.

Download or read book Dynamics of Underactuated Multibody Systems written by Robert Seifried and published by Springer Science & Business Media. This book was released on 2013-11-08 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: Underactuated multibody systems are intriguing mechatronic systems, as they posses fewer control inputs than degrees of freedom. Some examples are modern light-weight flexible robots and articulated manipulators with passive joints. This book investigates such underactuated multibody systems from an integrated perspective. This includes all major steps from the modeling of rigid and flexible multibody systems, through nonlinear control theory, to optimal system design. The underlying theories and techniques from these different fields are presented using a self-contained and unified approach and notation system. Subsequently, the book focuses on applications to large multibody systems with multiple degrees of freedom, which require a combination of symbolical and numerical procedures. Finally, an integrated, optimization-based design procedure is proposed, whereby both structural and control design are considered concurrently. Each chapter is supplemented by illustrated examples.

Download or read book Control of Flexible link Manipulators Using Neural Networks written by H.A. Talebi and published by Springer Science & Business Media. This book was released on 2001-01-29 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: Control of Flexible-link Manipulators Using Neural Networks addresses the difficulties that arise in controlling the end-point of a manipulator that has a significant amount of structural flexibility in its links. The non-minimum phase characteristic, coupling effects, nonlinearities, parameter variations and unmodeled dynamics in such a manipulator all contribute to these difficulties. Control strategies that ignore these uncertainties and nonlinearities generally fail to provide satisfactory closed-loop performance. This monograph develops and experimentally evaluates several intelligent (neural network based) control techniques to address the problem of controlling the end-point of flexible-link manipulators in the presence of all the aforementioned difficulties. To highlight the main issues, a very flexible-link manipulator whose hub exhibits a considerable amount of friction is considered for the experimental work. Four different neural network schemes are proposed and implemented on the experimental test-bed. The neural networks are trained and employed as online controllers.

This book was released on 2012-12-06 with total page 651 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flexibility is as acceptable an objective for today's industrial community as is automation. Thus, the title of this conference proceedings volume - Flexible Automation - reflects an added emphasis to the usual industrial automation. As with general automation that has impacted every component of the manufacturing office and plant, the identity of flexible automation can possess various forms and functions. The papers in this volume have been grouped into two main categories. One category deals with implementation of so-called "intelligent manufacturing". This means use of algorithmic methods and artificial intelligence approaches to various problems encountered in practical factory automation tasks. The placement of papers into five chapters of this part cannot be very precise, due to multidisciplinary nature and constant rapid change of the field. The categories are arranged starting from problems of enhancement of current factory settings, and followed by the papers addressing more specific issues of production planning, process technology and product engineering. The fifth chapter contains papers on the very important aspects of factory automation - problems of design, simulation, operation and monitoring of manufacturing cells.
