Abstract :
The aim of this paper is to show experimentally that a controller is able to reduce the rotor shaft torque variations in a variable speed wind turbine significantly. For that purpose an experimental model has been estimated from measured data. Based on this nominal model a stable controller has been designed such that the rotor shaft torque is minimized. The experimental results show the same amount of reduction, furthermore all nominal closed loop transfer functions are similar to the measured ones
