Nonlinear control of an induction motor in magnetic saturation

The control of an induction motor in magnetic saturation using a voltage input-output linearization technique is presented in this paper. The motor model, written in the stationary reference frame where all inductances are functions of magnetizing current is nonlinear with respect to the state variables and linear in the control. The controller decouples the flux control from the torque or speed even in the defluxing mode.
