This paper proposes an input-output linearization-based active power control strategy to maximize the energy production of a doubly fed induction generator (DFIG)-based wind energy conversion system (WECS). The DFIG-based wind turbine is a nonlinear system, and the nonlinear behavior will result in tracking errors. The proposed control strategy utilizing state feedback successfully deals with the nonlinear behavior existing in the WECS. Such a control will linearize the system input and output first. Then, the control loop and parameters can be designed by the linear system control algorithm. The simulations carried in MATLAB/Simulink demonstrate that the proposed control strategy is effective and promising.
