To increase the length of life and the stability of wind turbines, the output power of wind turbines should be restricted under the rated power. Especially, in order to guarantee the restriction, it is essential to use a pitch control above the defined rated wind speed. This paper presents a design method of a collective pitch controller for wind turbines using time-delay estimation (TDE). TDE estimates...
This paper describes a design of a wind turbine pitch controller based on the disturbance accommodating control (DAC) theory. Wind turbine systems generally operate under stochastic environments, such as random wind inputs and noise corrupted sensor signals. Especially wind inputs can be treated as persistent disturbances and DAC can play a role in reducing effects of wind disturbances. By doing this,...
