This paper proposes the fuzzy logic based variable step-size MPPT (Maximum Power Point Tracking) method for the stability at the
steady state and the improvement of the transient response in the wind power system If the change value of duty ratio is set on
stability of the steady state, MPPT control traces to maximum power point slowly. And if the change value is set on improvement of
the transient response, the system output oscillates at the maximum power point. By adjusting the step size with fuzzy logic, it can be
improved the MPPT response speed and stability at steady state when MPPT control is performed to track the maximum power point.
The effectiveness of the proposed method has been verified by simulations and experimental results.
