The Hybrid Electric Vehicles (HEVs) have the best of both worlds significant fuel saving, on demand power, lowered emission and quiet, smooth, emission-free electric motive power as well. Nowadays Permanent Magnet Synchronous Motor (PMSM) minimizes the drawbacks of the BLDC motor and it has high efficiency and their inherently high-power density they have been accepted as having great potential to compete with induction motor for HEV. Such that in this paper, The Field Oriented Control (FOC) method is implemented to control the speed and torque of the PMSM motor by using dq reference frame theory. The PI controllers are used to regulate the speed and the dq current to generate the gate pulses for switching of the inverter according to correction voltage. The whole system is simulated under the MATLAB Simulink environment. Results are carried out based on step change of speed and torque and we analyzed performance parameters such as gate pulse for the inverter, inverter output voltage and current, rotor angle, motor speed, dq current, and electromagnetic torque. Simulation results show that PMSM has a fast-dynamic response and tunable output speed and torque with minimum deviation.
