This paper discusses Direct-torque-control(DTC)-based fault-tolerance strategiesapplied to three fault-tolerant induction motor drive systems when they operate under single-phase open-circuit fault. Despite the fact that these drive systems have already been discussed in the literature, the reported papers always make use of Field-oriented-control(FOC)-based fault compensation strategies. In this way, performed simulations show that DTC-based strategies are feasible and are able to provide circular flux trajectory, which is the necessary condition for the motor operate properly.
