Nonlinear model predictive control of floating wind turbines with individual pitch control [PDF]
2014 American Control Conference, 2014 In this work a nonlinear model predictive controller with individual pitch control for a floating offshore wind turbine is presented. An aerodynamic model of the collective pitch control approach is extended by describing pitching and yawing moments based on rotor disk theory.
