    abstract     = "The increase in size, prize and power production of modern wind turbines continue to improve the overall economy of their installation and maintenance. A suitable place to install these mega wind turbines is on the sea as their is a more stable wind. These water based wind farms are confined to reefs near land where the construction of the foundations doesn’t become to expensive and problematic. It has been suggested to build floating wind turbines instead and thus enabling previous unsuited locations to become potential wind farms. This thesis investigates control of both wind turbines mounted on solid foundations and their floating counter parts.

The wind turbine operates over a wide wind speed range and the control objectives changes over that range. It has been investigated how to identify and switch between these different modes of operation. 

The turbulent nature of the wind causes the control of the gigantic structures to react within fractions of a second. Such rapid response should cross certain limits otherwise the fatigue of the actuator systems is greatly accelerated leading to uneconomic operation of the wind turbine. Model predictive control have been investigated as a method to keep within these constraints."
