Presented clearly and completely from the simple level to the application examples, this book provides information on induction machines and nonlinear control in a form that is suitable for engineers. The text explains the basic transformations used in electric machine theory and presents the properties of electrical machines based on multiscalar models. It discusses the nonlinear control of electrical machines, applies methods for synchronous machines to general theory, and describes methods of variable estimation. It also covers complete drive systems with estimations of unmeasured variables. In addition, the author includes simulation and experimental examples.
