A NEW ROBUSTE CONTROL BASED ON SUPER TWISTING SLIDING MODE OF A DUAL STAR INDUCTION GENERATOR FOR WIND TURBINE

Abstract

Traditional field oriented control using proportional integral (PI) regulator for the voltage DSIGs driven have many disadvantages such parameter tuning complication, mediocre dynamic performances and reduced robustness. Therefore, based on a d-q model of the DSIG supplied by two AC-DC converters, this article proposes an advanced control scheme based on super-twisting sliding mode (STSMC). The usual sliding mode control (SMC) has large chattering on the DC voltage result on the exit of the two rectifiers. With the purpose to solve this problem, the super twisting sliding mode control is used. The simulation results show the advantage of the proposed method in the efficiency and robustness against parameters variation of the DSIG.
