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 کاملMinimization of Torque Ripple in the Brushless Dc Motor Using Direct Torque Control
ermanent Magnet Brushless DC Motor (PMBLDC) is one of the best electrical drives that have increasing popularity, due to their high efficiency, reliability, good dynamic response and very low maintenance. Due to the increasing demand for compact & reliable motors and the evolution of low cost power semiconductor switches and permanent magnet (PM) materials, brushless DC motors become popular in...
متن کاملTorque ripple minimization in direct-drive systems
The open-loop torque control of synchronous motors with minimum torque ripple and minimum copper losses is presented. The control problem is viewed as an optimization problem for the nonlinear mapping from desired torque and position to the motor's phase currents. The performance of the controller to produce virtually ripple-free torque and to enhance the precision of position tracking is demon...
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...
متن کاملAn Improved Fixed Switching Frequency Direct Torque Control of Induction Motor Drives Fed by Direct Matrix Converter
a few papers have been interested by the fixed switching frequency direct torque control fed by direct matrix converters, where we can find just the use of direct torque controlled space vector modulated method. In this present paper, we present an improved method used for a fixed switching frequency direct torque control (DTC) using a direct matrix converter (DMC). This method is characterized...
