  • A Comparative Overview To DTC For Pmsm Driven Pure Electric Vehicles
    Fatih Korkmaz, Cankiri Karatekin University,Turkey
    ABSTRACT
    For many industrial applications that including electric motor, selecting of the appropriate motor type is keypoint for the application success and efficiency. This paper presents a comparative performance evaluation between direct torque controlled Brushless AC and Brushless DC motors which have been considered as traction motor on electric vehicles. Moreover, a short review to brushless AC and brushless DC motor technology and vector driver systems are also included. The main structure of the direct torque control method is presented and small-scale pure electric vehicle model is integrated to the motor control model. To make a fair comparison, the brushless AC and brushless DC motors modeled as having the same electrical parameters and simulated with same control model parameters. The simulation studies have shown that direct torque controlled brushless AC and brushless DC motors have similar performance as vehicle traction motor, and both motor types can be considered as a good candidate for electric vehicles applications.
  • A New Approach To DTC Method For BLDC Motor Adjustable Speed Drives
    Fatih Korkmaz, Cankiri Karatekin University,Turkey
    ABSTRACT
    This paper proposes a new approach to direct torque control (DTC) method for brushless direct current (BLDC) motor drives. In conventional DTC method, two main reference parameters are used as: flux and torque. In this paper, the new approach has been proposed to improve the BLDC motor dynamic performance. A main difference from the conventional method of it was that only one reference parameter (speed) was used to control the BLDC motor and the second control parameter (flux) was obtained from speed error through the proposed control algorithm. Thus, the DTC performance has been especially improved on systems which need variable speed and torque during operation, like electric vehicles. The dynamic models of the BLDC and the DTC method have been created on Matlab/Simulink. The proposed method has been confirmed and verified by the dynamic simulations on different working conditions.
