The three-phase induction motor is the most widely used drive in industry due to its sturdy construction and relatively affordable price. However, there a disadvantage that it difficult control torque speed dynamically separately. characteristics of are couple nonlinear. So be able To overcome these problems, decoupling method will separate between using DTC (Direct Torque Control) by setting v...

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 ripples for both electromagnetic torque and stator flux and a distortion of the stator current. To solve these problems, we have developed a new approa...

Direct Torque Control (DTC) is a control technique used in AC drive systems to obtain high performance torque control. The conventional DTC drive contains a pair of hysteresis comparators, a flux and torque estimator and a voltage vector selection table. The torque and flux are controlled simultaneously by applying suitable voltage vectors, and by limiting these quantities within their hysteres...
