A Sliding Mode Control with a PID Sliding Surface for Power Output Maximizing of a Wind Turbine

Abstract

The wind energy has many advantages, it does not pollute and it is an inexhaustible source. However, the
cost of this energy is still too high to compete with traditional fossil fuels, especially on the less windy sites.
The performance of a wind turbine depends mainly on three parameters: the power of the wind, the power
curve of the turbine and the generator’s ability to respond to the wind fluctuations. This article proposes a
robust control of a double-fed induction generator of wind turbine to optimize its production that means the
energy quality and efficiency. The proposed control reposes in the sliding mode approach using a PID
sliding surface, which contributes to the minimization of the static error and the number of the derivative
functions. Simulation results show good performances of this control.
