Wind is becoming one of the best options as a renewable energy source. In particular offshore wind turbines are gaining more and more appeal in view of exploiting high-speed winds and high wind availability thanks to the reduced impact on human and animal population with respect to onshore wind turbines. In recent years, this technology is having a big development especially in North Europe where there is a great wind resource. This thesis is part of a team project that has the aim of building a working test-bench to test actuators that could be applied in wind turbines giving as an input a simulated wind response implemented as a Hardware-In-The-Loop.
