Direct Torque Fuzzy Control of an AC Drive

In this paper, an application of the fuzzy logic scheme for direct torque fuzzy control (DTFC) of an Induction Motor (IM) AC drive is proposed. The proposed DTFC is based on fuzzy logic technique switching table is described and compared with conventional direct torque control (DTC). The comparison with DTC shows that the use of the DTFC reduces the torque, stator flux, and current ripples. The proposed fuzzy control strategy is simulated using MATLAB SIMULINK.
