| Summary: | Traditional vector control structures which
include proportional-integral (PI) regulator for the speed of a
doubly fed induction motor (DFIM) driven have some
disadvantages such as parameter tuning complications,
mediocre dynamic performances and reduced robustness. Thus,
based on the analysis of the mathematical model of a DFIM
supplied by two indirect inverters, this paper addresses a nonlinear
control algorithm based on high order sliding mode. The
conventional sliding mode control has large chattering on the
electromagnetic torque developed by the DFIM. In order to
solve this problem, the second order sliding mode technique is
used. The simulation results show the effectiveness of the
proposed method especially in chattering-free behavior,
response to sudden load torque variations and robustness
against machine parameters variations. |
