This paper presents the basic structure, the model, and the design of a torque controller for an electric vehicle (EV). The proposed EV is the transformation of a conventional vehicle with internal combustion engine to electric vehicle, where the original traction system based on an internal combustion engine is replaced by an electric traction system. The controller is based on the technique of direct torque control (DTC) plus a term that compensates the ohmic drop in the stator windings of the induction motor (IM). In order to obtain a constant switching frequency, the space vector modulation (SVM) technique is used to generate the pulses of the inverter. In order to test the performance of the control proposed, numerical results are presented, which are compared with conventional DTC scheme. [ABSTRACT FROM AUTHOR]
