Abstract: In this paper a Comparative analysis is made between Indirect field oriented control and Space Vector Modulation based Direct torque control (SVM-DTC) methods to regulate the performance of the propulsion motor of a Battery Electric Vehicle(BEV) with road load under NEDC drive cycle. Owing to the splendid characteristics like rapid torque control and higher efficiency, the Induction Motor (IM) is adopted as the preeminent for BEV propulsion motor. The most significant techniques used for propulsion motor torque and speed control are Indirect field oriented control (IFOC) and Space Vector Modulation based direct torque control (SVM-DTC).In IFOC the propulsion motor control is achieved by synthesizing stator currents from two quadrature components, corresponding to flux and torque respectively. In SVM-DTC decoupling and linearization of current vectors through coordinate transformation is eradicated and a reference stator flux vector originated by the adaptive motor model provides d and q axis reference voltages fed to SVM. Simulation results are explored to accentuate the performance of the propulsion motor with road load for both methods under NEDC drive cycle.
