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 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.
