Direct Torque Control Of IM Drives Using Fuzzy Logic Controller

This study deals with the direct torque control (DTC) of the induction motor. This type of control allows decoupling control between the flux and the torque without the need for a transformation of coordinates. However, the DTC scheme has a high ripple for both electromagnetic torque and stator flux and a distortion of the stator current. To solve these problems, we have developed a new approach of DTC scheme making use of fuzzy logic.
