Torque Ripple Minimization Strategy for Direct Torque Control of Induction Motor Using Fuzzy Scheme
The direct torque control (DTC) speed control scheme of an induction motor surpasses the vector control in the sense that it controls the torque directly and does not use transformations and current modulator. In the traditional direct torque control (DTC) of induction motor, the low order harmonic component of stator current is very large when the motor is running at low speed. It leads to hig...
متن کاملTorque Ripple minimization techniques in direct torque control induction motor drive
This paper considers direct torque control strategies in induction motor drive to minimize torque ripples. Spacevector modulation and modified space vector control concept is implemented to design the controller. Basic DTC method suffers from torque ripples problem and switching frequency variation.[1] Torque ripples are minimized using space vector modulation technique but execution time in th...
متن کاملDirect Torque Control of Induction Motor Using Fuzzy Logic Controller
The paper presents fuzzy logic based direct torque control (DTC) scheme of an induction motor (IM) and its comparative study using intelligent techniques under varying dynamic conditions are discussed. Direct torque control (DTC) of an induction motor fed by a voltage source inverter is a modest scheme that does not need lengthy computation time and can be implemented without pulse encoders but...

متن کاملDirect Torque Control of Induction Motor Using Multilevel Inverter
. This paper proposes the three level diode clamped multilevel inverter fed direct torque control of induction motor. The proposed multilevel inverter has the advantages of fewer harmonic in the output and low torque ripples. The switching table direct torque control scheme is adopted due to the simplicity of the control algorithm. The PI speed controller is used in the outer loop. To demonstra...
