development and implementation of an optimized control strategy for induction machine in an electric vehicle
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
15 صفحه اولInvestigating Direct Torque Control of Six-Phase Induction Machines Under Open Phase Fault Conditions
This paper presents analysis and evaluation of classical direct torque control(DTC), for controlling a symmetrical six phase induction motor (SPIM) under open phasefault conditions. The machine has two three-phase windings spatially shifted by 60 electricaldegrees. The strategy of the proposed method consists of choosing the switching modesaccording to the configuration of living phases in such...
متن کاملStudy of Direct Torque Control Scheme for Induction Motor Based on Torque Angle Closed-Loop Control
Abstract: For disadvantages of the large flux and torque ripple and current waveform distortion of Direct Torque Control (BASIC-DTC), the DTC scheme for induction motor based on torque angle closed-loop control was presented and the proposed scheme was realized with three methods of torque angle closed-loop control. The main characteristics of three methods of torque angle closed-loop control f...
متن کاملEvaluation of Speed and Torque Estimations for the EKF-based Direct Torque Control in Induction Machines
Abstract Accurate estimations of unmeasurable variables are required for increasing the performance of sensorless induction motor drives. This can be achieved if the required variables are accurately estimated with a well-established observer. The paper presents an extended Kalman filterbased direct torque control to investigate the estimations of speed and torque under challenging rotor and st...
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...
