Motor and Regenerative Braking Operations for an Electric Vehicle using Field Oriented Control

Regenerative Braking is one of the solutions to the problems linked to energy storage in Electric Vehicle, as it helps to boost its autonomy. In this work we present analysis, modelling and simulation of indirect field orientation control of Permanent Magnet Synchronous Machine, putting into consideration the motor mode and regenerative braking mode. A bidirectional DC-DC converter controls the DC bus which supplies the PMSM via the three phase inverter and allows power flow in the opposite direction. The dynamics of a vehicle with a load torque applied to a motor shaft will be examined. The battery stores the energy produced during the braking phase. The Matlab/Simulink software will be used to simulate an urban Electric Vehicle movement in order to test the effectiveness of the regenerative braking on the electric vehicle autonomy.
