Induction motors are presently used in many electric vehicle applications. As a result, their control methods have received a lot of attention. One of the efficient method of induction motor control is the direct torque control (DTC). In this paper, a design method for direct torque control of induction motor has been developed. A Verilog hardware description language is used to implement the developed DTC model on Nexys 2 FPGA kit. Field programmable gate array (FPGA) has many coherent advantages such as fast response, reliable, flexible, robust against load variations and programmable architecture. The same algorithm is designed and simulated using Matlab/Simulink tool to make comparison with the designed model on FPGA which shows reduction in flux and torque ripples. Also, the simulated results are validated experimentally.
