Abstract

Abstract: Wind turbine size has increased exponentially for the last twenty years. With the increase in size the control systems for variable speed pitch regulated machines play a greater role, since they are used for other tasks than just regulating generator speed. The structural dynamics impact directly on the achievable control system performance becoming more restrictive as the size of wind turbine increases. To make this dependence explicit, the relationships between performance measures of the control system and wind turbine structural dynamic characteristics are derived
