Super-twisting sliding mode control for brushless doubly fed reluctance generator based on wind energy conversion system

Abstract

Introduction. Recently, wind power generation has grown at an alarming rate in the past decade and will continue to do so as power electronic technology continues to advance. Purpose. Super-twisting sliding mode control for brushless doubly-fed reluctance generator based on wind energy conversion system. Methods. This paper deals with the robust power control of a grid-connected brushless doubly-fed reluctance generator driven by the variable speed wind turbine using a variable structure control theory called sliding mode control. The traditional sliding mode approach produces an unpleasant chattering phenomenon that could harm the system. To eliminate chattering, it is necessary to employ a high-order sliding mode controller. The super-twisting algorithm is one type of nonlinear control presented in order to ensure the effectiveness of the control structure we tested these controllers in two different ways reference tracking, and robustness. Results. Simulation results using MATLAB/Simulink have demonstrated the effectiveness and robustness of the super-twisting sliding mode controller.

A novel intelligent control approach for wind energy conversion systems with synchronous reluctance generators

“…The exploration and implementation of nonlinear control strategies have marked a significant improvement in the performance and efficiency of wind energy systems, as noted in several studies. [32][33][34][35][36][37][38][39][40][41][42][43] However, these techniques often encounter challenges, including sensitivity to variable parameters and a deficit in real-time adaptability. As WPCSs continue to develop, overcoming these hurdles remains a critical focus for researchers and industry professionals.…”

“…The efficiency of the SMC is validated through Matlab/Simulink simulations, showcasing its ability to deliver consistent, high‐quality energy to the electrical grid. In Oualah et al, 34 the paper focuses on the robust power control of a grid‐connected brushless doubly‐fed reluctance generator (BDFRG) driven by a variable speed WT using a variable structure control theory called sliding mode control. The paper aims to address the chattering phenomenon associated with traditional sliding mode control by employing a high‐order SMC, specifically the super‐twisting algorithm.…”
