Abstract: With the increasing need of electric vehicles (EV), necessary development is required to get reliable, efficient and economical drives for electric propulsion. Electric propulsion system using Induction Motor drive (IM) is becoming so popular because of its reliability, technological maturity and low cost. Field Orientation Control (FOC) is so popular in controlling the IM, but it has disadvantages like sensitive to parametric variation, external disturbance, load variation and also algorithm takes more time for execution, hence it requires a very fast microprocessor with high millions of instructions per second (MIPS) for implementation. In this paper, IM is controlled by using Direct Torque Control (DTC) technique because of its simple configuration and gives quick response. The mathematical model takes into account of the inverter, IM dynamics and vehicle aerodynamics. In this paper, the response of the IM with DTC for EV load for driving cycle consists of starting, acceleration, constant speed and deceleration modes are explained and validated using MATLAB/SIMULINK.
