Abstract
To capture wind energy and to produce electrical
power, many conversion systems have been proposed. This
work treats also the modeling and the control of dual stator
induction generator DSIG integrated in wind energy conversion
system. In order to increase the flow of the power
to the grid and to ensure an optimum operating point, it is
very important to act on the generator side controllers and
the conversion system output variables. The Proportional
integral PI controllers have been widely used to control
alternative machines. In this case, the inverters, which fed
the DSIG, are controlled simultaneously with a displaced
angle of 30 . So, the synthesis PI gains still difficult. To
solve this problem, a nonlinear backstepping control is
proposed. For that, the suggested study presents the comparison
of the performances of the two strategies. Different
simulation tests are conducted to evaluate the efficiency
and the validity of the proposed control strategies. We
notice that in the steady state, the two controls allow the
same performance (tracking). In transient mode, the
backstepping command is better in terms of response time
and overshoot.
