Summary:In this paper, the nonlinear sliding-mode torque and flux control
combined with the adaptive backstepping approach for an induction motor
drive is proposed. Based on the state-coordinates transformed model
representing the torque and flux magnitude dynamics, the nonlinear
sliding-mode control is designed to track a linear reference model.
Furthermore, the adaptive backstepping control approach is utilized to
obtain the robustness for mismatched parameter uncertainties. With the
proposed control of torque and flux amplitude, the controlled induction
motor drive possesses the advantages of good transient performance and
robustness to parametric uncertainties, and the transient dynamics of
the induction motor drive can be regulated through the design of a
linear reference model which has the desired dynamic behaviors for the
drive system. Finally, some experimental results are demonstrated to
validate the proposed controllers
