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, wind turbines suffer less from mechanical fatigue loads and their lifespan can be increased. Because wind disturbances we must accommodate are stochastic, we design DAC for stochastic plants and compare with other controllers not considering stochastic conditions to verify the performances of our proposed controller.
