Direct torque control for dual-three phase induction machine with one stator phase opened
A direct torque control (DTC) strategy for dual-three phase induction machine with one stator winding open-circuited is discussed in this paper. An optimums election scheme of space voltage vector is proposed based on fuzzy control and direct torque control. The largest space voltage vectors are selected to control the machine. To verify the presented method, fuzzy direct torque control of dual-three phase induction machine is simulated. The simulation results show that the machine in fault state is still effectively controlled, and good dynamic performances are obtained with the proposed method.
