Abstract

In work we developed Direct torque control (DTC) is an emerging technique for controlling PWM inverter-fed induction motor (IM) drives. It allows the precise and quick inspection of the IM flux and torque without calling for complex control algorithms. In principle, moreover, it requires only the knowledge of the stator resistance. The application by reviewing the basic operation of an IM and a PWM inverter using the space vector theory. The field-oriented (FO) control of an IM drive is also discussed. Then the concept of direct self-control (DCS), space vector modulation (SVIM) are described. The ST strategy is dealt with in detail, discussing the results which can be obtained with different choices of the switching table. Problems associated with the selection of the amplitude of the hysteresis bands of the flux and torque controllers are illustrated using experimental data. Modulation technique can be used in both open and closed-loop motor control applications. A device which consist of Single Phase Induction Motor and it has single phase winding which is winding on the stator of the motor and a winding placed on the rotor. A pulsating magnetic field is produced, when a phase supply energizes the stator winding of the single-phase induction motor shown below. The developed control technique is based on the comparison of the high-frequency output signal with the input source, similar to the one used in voltage source inverter although the pulsing single is widely employed for control of voltage source inverter
