Abstract EN
An active and optimum controller is applied to regulate the power output from a wind turbine rotor.
The controller is synthesized in two steps.
The first step defines the equilibrium operation point and ensures that the desired equilibrium point is stable.
The stability of the equilibrium point is guaranteed by a control law that is synthesized by applying the methodology of model predictive control (MPC).
The method of controlling the turbine involves pitching the turbine blades.
In the second step the blade pitch angle demand is defined.
This involves minimizing the mean square error between the actual and desired power coefficient.
The actual power coefficient of the wind turbine rotor is evaluated assuming that the blade is capable of stalling, using blade element momentum theory.
This ensures that the power output of the rotor can be reduced to any desired value which is generally not possible unless a nonlinear stall model is introduced to evaluate the blade profile coefficients of lift and drag.
The relatively simple and systematic nonlinear modelling and MPC controller synthesis approach adopted in this paper clearly highlights the main features on the controller that is capable of regulating the power output of the wind turbine rotor.
