The control of electrical machines depends on their use (nature of the load, operating states, etc.). This use determines control laws. The mechanics are also very important, because they affect performance. Operating safety of machines is essential for industrial applications. All these issues are addressed in this title, featuring contributions from a range of authors who are specialists in their particular field. Different ways to control a set of machines coordinating their actions are also presented. This book is primarily aimed at those involved in complex systems design, but engineers in a range of fields will also find this a useful source of information.
