High-performance power maximization based wind energy conversion system using super twisting sliding mode approach

This article presents high-performance power maximization based on the super twisting sliding mode approach. The second-order sliding mode control is proposed in order to ensure the maximization of the power of the wind system to the network and to overcome the problem of chatter associated with the traditional first-order sliding mode control. The continuous super twisting control law is robust to uncertainties with respect to parameter variations and able to reduce the chattering effect while preserving desirable properties. Therefore, it protects the wind energy conversion system from overcurrent and reduces the mechanical vibration in the rotor caused by the effect of chatter. The effectiveness of the control algorithms was studied by numerical simulation using MATLAB/Simulink software.
