Torque 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 کاملTorque 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 کاملA Fuzzy Based Duty Ratio Approach to Torque Ripple Minimization Strategy for Direct Torque Control of Induction Motor
In the conventional DTC, the selected voltage vector is applied for the whole switching period regardless of the magnitude of the torque error. This can result in high torque ripple. A better drive performance can be achieved by varying the duty ratio of the selected voltage vector during each switching period according to the magnitude of the torque error and position of the stator flux. A dut...

The main objective of this research paper is to deliver the selection criteria of PMBLDC Motor for certain industrial applications. In general, Industries uses large Horsepower (HP) Brushless DC Motors as the special drives. These motors offer low starting currents with high starting torque, and the ability to supply reactive KVA to the plant system if desired. For specific industrial applicati...
متن کاملDirect Torque Control of Induction Motors with Fuzzy Minimization Torque Ripple
Direct torque control (DTC) is a new method of induction motor control. The key issue of the DTC is the strategy of selecting proper stator voltage vectors to force stator flux and developed torque within a prescribed band. Due to the nature of hysteresis control adopted in DTC, there is no difference in control action between a larger torque error and a small one. It is better to divide the to...
