Modern power electronic converters are involved in a very broad spectrum of applications: switched-mode power supplies, electrical-machine-motion-control, active power filters, distributed power generation, flexible AC transmission systems, renewable energy conversion systems and vehicular technology, among them.

Power Electronics Converters Modeling and Control teaches the reader how to analyze and model the behavior of converters and so to improve their design and control. Dealing with a set of confirmed algorithms specifically developed for use with power converters, this text is in two parts: models and control methods. The first is a detailed exposition of the most usual power converter models:

·        switched and averaged models;

·        small/large-signal models; and

·        time/frequency models.

The second focuses on three groups of control methods:

·        linear control approaches normally associated with power converters;

·        resonant controllers because of their significance in grid-connected applications; and

·        nonlinear control methods including feedback linearization, stabilizing, passivity-based, and variable-structure control.

Extensive case-study illustration and end-of-chapter exercises reinforce the study material.

Power Electronics Converters Modeling and Control addresses the needs of graduate students interested in power electronics, providing a balanced understanding of theoretical ideas coupled with pragmatic tools based on control engineering practice in the field. Academics teaching power electronics will find this an attractive course text and the practical points make the book useful for self tuition by engineers and other practitioners wishing to bring their knowledge up to date.

Optimal Control of Wind Energy Systems is a thorough review of the main control issues in wind power generation, covering many industrial application problems. A series of control techniques are analyzed and compared, starting with the classical ones, like PI control and gain-scheduling techniques, and continuing with some modern ones: sliding mode techniques, feedback linearization control and robust control. Discussion is directed at identifying the benefits of a global dynamic optimization approach to wind power systems. The main results are presented and illustrated by case studies and MATLAB®/Simulink® simulation. The corresponding programmes and block diagrams can be downloaded from the book’s page at springer.com. For some of the case studies presented, real-time simulation results are available. Control engineers, researchers and graduate students interested in learning and applying systematic optimization procedures to wind power systems will find this a most useful guide to the field.
