Abstract

This paper deals with the modelling and control of a three-phase induction machine supplied by three independent voltage sources when one phase is open-circuited. The modelling of the overall system leads to design a dedicated controller tuned with the generalised stability margin method in order to reduce the pulsating torque. The consequences of the new closed-loop control on the induction machine and the VSI are evaluated to quantify the currents, voltages and copper losses increasing. Finally, simulation and experimental results are achieved and show the global performances of this ripple torque reduction method.
