Understanding of complex engineering and mathematical transformations is a prerequisite before implementation of Direct Torque and Field Orientation Control Strategies in Real Time Environment. Mathematical models of DTC/FOC are developed from concept to operate in off line simulation environment. Comparative study is carried out to understand implications of DTC & FOC on overall performance of electric drive train while negotiating different driving cycles. Dual mode motor control strategy viz. V/f + DTC and V/f + FOC is proposed to improve drivability and to maximize efficiency of electric drive train. In development of HEV, complete electrical drive train assisted with power electronics need to build mathematically to understand the response of control strategies to Torque and Speed demand during cycle negotiations. This also felicitate in reducing the risk of discovering any error in the stage of implementation of control on actual hardware. Electric drive performance simulation is carried out with developed controls using real time platform d-SPACE RTI 1104. Hardware - In-Loop (HiL) technique is used for evaluation of these algorithms in real time environment. This is followed with an experiment performed in lab on 3 kW Induction motor with down scaled data of demand torque and speed using DTC and FOC to validate these controls experimentally. © International Science Press.
