The British Textile Trade in South America in the Nineteenth Century

by Manuel Llorca-Jaña

2012 · Cambridge University Press

This is the first work on British textile exports to South America during the nineteenth century. During this period, textiles ranked among the most important manufactures traded in the world market and Britain was the foremost producer. Thanks to new data, this book demonstrates that British exports to South America were transacted at very high rates during the first decades after independence. This development was due to improvements in the packing of textiles; decreasing costs of production and introduction of free trade in Britain; falling ocean freight rates, marine insurance and import duties in South America; dramatic improvements in communications; and the introduction of better port facilities. Manuel Llorca-Jaña explores the marketing chain of textile exports to South America and sheds light on South Americans' consumer behaviour. This book contains the most comprehensive database on Anglo-South American trade during the nineteenth century and fills an important gap in the historiography.

Energy-Based Control of Electromechanical Systems

This book introduces a passivity-based approach which simplifies the controller design task for AC-motors. It presents the application of this novel approach to several classes of AC motors, magnetic levitation systems, microelectromechanical systems (MEMS) and rigid robot manipulators actuated by AC motors. The novel passivity-based approach exploits the fact that the natural energy exchange existing between the mechanical and the electrical subsystems allows the natural cancellation of several high order terms during the stability analysis. This allows the authors to present some of the simplest controllers proposed in scientific literature, but provided with formal stability proofs. These simple control laws will be of use to practitioners as they are robust with respect to numerical errors and noise amplification, and are provided with tuning guidelines. Energy-based Control of Electromechanical Systems is intended for both theorists and practitioners. Therefore, the stability proofs are not based on abstract mathematical ideas but Lyapunov stability theory. Several interpretations of the proofs are given along the body of the book using simple energy ideas and the complete proofs are included in appendices. The complete modeling of each motor studied is also presented, allowing for a thorough understanding. Advances in Industrial Control reports and encourages the transfer of technology in control engineering. The rapid development of control technology has an impact on all areas of the control discipline. The series offers an opportunity for researchers to present an extended exposition of new work in all aspects of industrial control.
