An enhanced robust super-twisting sliding mode control MPPT approach for a stand-alone wind energy conversion system equipped with PMSG

Due to uncertainties associated with the permanent magnet synchronous generator (PMSG)-based wind energy conversion system (WECS), the traditional control method, which lacks robustness, may struggle to achieve the performance criteria of control. This paper proposes the implementation of a highly efficient non-linear control method known as the super twisting algorithm for the outer control loop, while the vector control technique was carried out for the inner control loop. The main purpose is to enhance the production of wind energy by maximizing the output power of a variable speed wind turbine generator. In order to assess the effectiveness of the suggested method in terms of reference tracking, settling time, and stability in the presence of varying wind conditions, the MATLAB/Simulink environment was utilized to create the complete system. Additionally, a comparison was made with a traditional PI controller. The results obtained demonstrate superior performance when compared to traditional controllers.
