Rapid progress in power electronics, microelectronics, and modern control technology during the past three decades has made possible the use of brushless servomotors in motion control. This application can provide high productivity and improved product quality on the production line and in manufacturing systems and is the basis of modern industrial automation and economic development. The book is intended as a practical introduction for engineers and students who are not familiar with servomotors and motion control. The control methods described are useful for practising engineers who want to deepen their knowledge of motion control in manufacturing systems. It covers the interdisciplinary areas of power electronics, drive electronics, mechatronics and control electronics, power semiconductor devices, microprocessors, circuits, controllers, sensors, magnetic materials, design methods, and applications.
