In this work, we are interested in improving the performance of a doubly-fed induction generator (DFIG)-based wind system, by applying a sliding mode control strategy. The objective is the regulation of the active and reactive power, also the voltage and the frequency of the signal injected into the distribution network. The model proposed for the control is based on the sliding mode technique with performance estimators. The proposed model was validated by a simulation on MATLAB/Simulink.
In this work, we are developing a new strategy for controlling wind systems based on the DFIG Generator. The SMC sliding mode technique is based on the principle of Lyapunov stability in order to make a nonlinear system close to linearity. The use of such a technique with an improvement in regulators to eliminate the Chattering phenomenon shows a great improvement in the performance of wind systems. which is based on performance estimators to improve the quality of the system. The energy quality at the output of the wind system will be injected into the distribution network according to international standards. The proposed model is validated on the Matlab & Simulink environment to test trajectory tracking and robustness.
