Chapter 10 is on nonlinear control of induction motors for speed regulation with maximal energetic efficiency. It is noticed that optimization cannot be properly coped with if the magnetic circuit nonlinearity is not accounted for. The controller includes an optimal flux reference generator (optimal in the sense of minimal stator current consumption) and a nonlinear regulator obtained using the backstepping design technique. It is shown that the controller regulates well the motor speed and the rotor flux in presence of wide-range variations of the machine speed reference and the load torque.
