Abstract: A simplified Direct Torque Control (DTC) strategy for symmetrical six phase induction motor drives with ANFIS and PI controller is discussed in this paper. The coils of the six phase induction motor are symmetrically arranged and angle between two consecutive phases is 60o. A simplified DTC technique is used to regulate the torque and hence control the speed. The simulation was conducted at starting, speed reversal, speed change, sudden load torque disturbances and faulty conditions. Comparison of the results establish the acceptable performance of both the ANFIS and PI controllers obtained after simulation of the Drive System in C++ environment.
