The problem of batteries in electric vehicles is one of
the biggest problems. Late charging and premature discharge of
the battery makes it difficult to travel to distant ranges on
electric vehicles. For this reason, it is necessary to regularly use
the energy that is charged in the battery. At the same time, the
torque to be produced in the electric vehicle must be sufficiently
low to oscillate and the torque must not sinusoidally move. The
fluctuation in torque also affects motor speed. Thus, it is
necessary to improve the speed control performance by reducing
the fluctuation of the torque the least. Direct Torque Control
(DTC) and field oriented control (FOC) methods become an
industrial standart for induction motor driving. The aim of this
paper is to compare the performance of field oriented and direct
torque control of 3-phase induction motor. Speed, torque, stator
currents, stator flux linkages, flux plane characteristic of
induction motor which is controlled by DTC and FOC methods,
are obtained from simulation applying reference speed to
induction motor. Furthermore, output energy and power by
induction motor, are calculated and plotted. The analysis of this
chracteristics are simulated by Matlab. İn this study, energy
efficiency is achieved by consuming less power through the
proposed method.
