The design of the controller is based on a reduced order model of the machine, and the control variables are non-discontinuous currents, obtained integrating a discontinuous auxiliary control signal. The phase voltages are then generated using a current regulated pulse width modulation inverter, while the rotor flux value is obtained by means of a simple observer. The convergence properties of the proposed control strategy are studied in the paper, and verified in simulation. publisher: IEEE date: 2009-06 type: Book Section type: PeerReviewed identifier: Ferrara, Antonella and Rubagotti, Matteo A sub-optimal second order sliding mode controller for current-fed induction motors.
