On the discrete-time modelling and control of induction motors with sliding modes

In this work a discrete-time controller for an induction motor is proposed. State feedback and diffeomorphism are applied to the plant dynamics in order to be finitely discretized. Then, on the base of the sampled dynamics, a discrete-time controller is derived, achieving speed and flux modulus tracking objectives. Finally, a reduced order observer is designed for rotor fluxes and load torque observation.
