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.
