Maximum Power Point Tracking based on Backstepping Control of Wind Turbinefull text in English

摘要

In this paper, a nonlinear backstepping controller is proposed to maximize the power extraction of a variablespeed wind turbine. This algorithm works in the partial load region. It has been used to control the windturbine speed so that it reaches the desired value which corresponds to the maximum power point. Completesimulation of the MPPT system validates the efficiency of the proposed backstepping control law. Compared tothe conventional PI controller usually used, the backstepping control allows to exhibit excellent transientresponse during large range of operating conditions.
