Digital Control of Electrical Drives offers insight into electric drives and their usage in motion control environment. It provides links among electrical machine and control theory, practical hardware aspects, programming issues, and application-specific problems. The book prepares the reader to understand the key elements of motion control systems, analyze and design discrete-time speed and position controllers, set adjustable feedback parameters, and evaluate closed-loop performances. Basic engineering principles are used to derive the controller structure in an intuitive manner, so that designs are easy to comprehend, modify, and extend. Digital Control of Electrical Drives helps the reader acquire practical skills in designing discrete-time speed and position controllers. Each chapter is followed by a set of MatlabR and SimulinkR tools which help readers master the phases of design, tuning, simulation, and evaluation of discrete time controllers, and foresee the effects of control solution on the overall motion control system. Readers will also understand the present performance limits of digital motion controllers. Contents Preface 1 Speed Control 1.1 Basic structure of the speed-controlled system Problems 2 Basic Structure of the Speed Controller 2.1 Proportional control action 2.1.1 Open-loop and closed-loop transfer functions 2.1.2 Load rejection of the proportional speed controller 2.1.3 Proportional speed controller with variable reference 2.

From the Back Cover Digital control systems are becoming increasingly prevalent and important within industry. In recent years significant progress has been made in their analysis and design - particularly within the areas of microprocessors and digital signal processors. The traditional approach to teaching digital control assumes an understanding of analog control theory; Digital Control, however, teaches the fundamentals of the topics, assuming no prior knowledge of control engineering. Organised into five sections, it discusses modelling, signal processing and identification of plants from measurements, as well as the transfer function approach to, and state space techniques for, control design. * Teaches the fundamentals of digital control, enabling the student to exploit the complete potential of digital systems. * Presents a number of control techniques including proportional-integral-derivative (PID), pole placement, internal model, minimum variance, model predictive and linear quadratic Gaussian control and their extensions. * Provides an extensive introduction to digital signal processing, an essential component to the understanding and implementation of digital controllers; and to the identification of plant models, an important topic in this information era. * Includes examples, problems and solutions as well as accompanying MatLAB code. Digital Control offers an advanced and self-contained textbook to senior undergraduates and postgraduates in chemical Read more...

To the student English Grammar in Use Supplementary Exercises is for intermediate and advanced students who want extra practice in grammar, without help from a teacher. There arc 200 exercises in this new edition. Each exercise relates to a unit or units in English Grammar in Use new edition 2004, with the unit number(s) at the top of the page. All the answers arc given in the Key (pages 121-136). Some exercises ask you to use your own ideas. For these, you can check the Example answers in the Key. You can use this book if you don't have English Grammar in Use, but for an explanation of the grammar points, you need to check in English Grammar in Use. The grammar points covered in the book are not in order of difficulty, so you can go straight to the parts where you need the most practice. Where there arc several exercises on one grammar point, however, the easier ones come first. It's a good idea to do each exercise, check your answers and then go on to the next one. Many of the exercises are in the form of emails, letters, conversations or short articles. You can use these as models for writing or speaking practice. To the teacher English Grammar in Use Supplementary Exercises offers extra practice of most of the grammar points covered in English Grammar in Use new edition 2004. Much of the language is contextualised within dialogues, emails, letters, articles etc., encouraging students to consider meaning as well as form. The book can be used as self-study Read more...

Relativistic cosmology has in recent years become one of the most active and exciting branches of research, often considered to be today where particle physics was forty years ago, with major discoveries just waiting to happen. Consequently the part most affected by this second edition is the last part on cosmology. But there are additions, improvements, and new exercises throughout. _ The book's basic purpose is unchanged. It is to make relativity come alive conceptually, and to display the grand theoretical edifice that it is, with consequences in many branches of physics. The emphasis is on the foundations, on the logical subtleties, and on presenting the necessary mathematics - including differential geometry and tensors - but always as late and in as palatable a form as possible. Aided by over 300 exercises, the book seeks to promote an in-depth understanding, and the confidence to tackle any basic problem in relativity. Review 'Rindler's writing is elegant, yet compact and logically precise. ... this book should be on the shelf of all who are intrigued by the startling modern advances in our understanding of space and time. ' American Journal of Physics 'An outstanding introductory treatise by one of the masters of the subject, this book belongs to the shelves of every physics library.' Foundations of Physics '... a self-contained and balanced work. Every sentence hits home, and no word is superfluous. Each chapter ends with a set of well-chosen and instructiv Read more...
