Abstract-The emergence of wind turbine systems for electric power generation can help satisfy the growing global demand. This paper proposes a control strategy to maximize the wind energy captured in a variable speed wind turbine, with an internal induction generator, at low to medium wind speeds. The proposed strategy controls the tip speed ratio, via the rotor angular speed, to an optimum point at which the efficiency constant (or power coefficient) is maximal for a particular blade pitch angle and wind speed. This control method allows for aerodynamic rotor power maximization without exact wind turbine model knowledge.

“…In this paper, 1 we have extended the previous results given in Ozbay et al (2008) and Sivrioglu et al (2008) to a more sophisticated variable-speed wind turbine model, and present a novel robust backstepping approach for the control problem of the variable-speed wind turbine with a permanent magnet synchronous generator (PMSG). Specifically, to compensate for the undesirable effects of parametric uncertainties, of both mechanical and electrical subsystems, a differentiable robust controller is proposed.…”

“…In Ozbay, Zergeroglu, and Sivrioglu (2008) and Sivrioglu, Ozbay, and Zergeroglu (2008), the control design in Song et al (2000) was extended to compensate for the uncertainties in both electrical and mechanical subsystems. In Sivrioglu et al (2008), the issues of external disturbances and modeling errors were also addressed.…”

In this study, a robust backstepping approach for the control problem of the variable-speed wind turbine with a permanent magnet synchronous generator is presented. Specifically, to overcome the negative effects of parametric uncertainties in both mechanical and electrical subsystems, a robust controller with a differentiable compensation term is proposed. The proposed methodology ensures the generator velocity tracking error to uniformly approach a small bound where practical tracking is achieved. Stability of the overall system is ensured by Lyapunov-based arguments. Comparative simulation studies with a standard proportional-integral-type controller are performed to illustrate the effectiveness, feasibility and efficiency of the proposed controller.

“…The standard region 2 (power capture maximization mode) control scheme used for variable speed wind turbines (τ = kω 2 , where τ is the control torque, ω is the rotor angular speed and k is a control gain) has some disadvantages that can result in unsatisfactory power capture. First, the control gain, k, is difficult to be determined due to the dependence on exact model knowledge (maximum power efficiency constant and optimal tip-speed ratio).…”

This paper proposes a control strategy to maximize the wind energy captured in a variable speed wind turbine, with an internal induction generator, at low to medium wind speeds. The proposed strategy controls the tip-speed ratio, via the rotor angular speed, to an optimum point at which the efficiency constant (or power coefficient) is maximum for a particular blade pitch angle and wind speed. This control method allows for aerodynamic rotor power maximization without exact wind turbine model knowledge. Representative numerical results demonstrate that the wind turbine can be controlled to achieve near maximum energy capture.
