Résumé

A squirrel cage induction motor has been the
workhorse in industry for variable speed applications in a
wide power range that covers from fractional horsepower to
multi megawatts. But the control and estimation of ac drives
in general are considerably more complex than those of dc
drives. The advent of vector control techniques has partially
solved induction motor control problems. However, these
techniques are very sensitive to the variation of motor parameters,
result in an undesirable coupling between the flux and
the torque of the machine, and loss of dynamic performance.
To solve these problems this paper presents a synthesis of
two control strategies, for controlling speed and rotor flux of
induction motor (IM) via nonlinear control (NLC) and sliding
mode control (SMC). Computer simulations are carried
out to show the robustness of the proposed method against
rotor resistance and load torque variations. The performance
of SMC has been successfully compared with nonlinear control.
