This book discusses about the new techniques of power generation control of oscillating water column (OWC) using airflow control and maximum power point tracking of OWC using rotational speed control. OWCs harness energy from the oscillation of the seawater inside a chamber or hollow caused by the action of waves. This book presents the mathematical modeling and control techniques used by OWCs. Introducing new concepts to studies of wave energy to provide fresh perspectives on energy extraction and efficiency problems, the book will be a valuable resource for researchers and industrial companies involved in thermal energy and coastal engineering. It will also be of interest to students, as it broadens their view of wave energy.
