Nonlinear synergetic control of wind turbine for maximum power point tracking

This paper focuses to improve wind turbine systems efficiency, in other words, to maximize the output power delivered by the wind turbine. To do this it is necessary to have a good controller. In this study, we use a nonlinear synergetic controller. Synergetic control theory is applied to reach the maximum power point tracking (MPPT) of a variable speed energy conversion system. A comparison with the robust sliding mode control allowed us to see the effectiveness of the proposed controller. These controllers are tested in a Simulink/Matlab environment. Simulation results present good performance compared to the classical sliding mode controller, as well as to the synergetic controller with linear macro-variable.
