Field-Oriented Control (FOC) for Permanent Magnet Synchronous Motors (PMSM) In Electric Vehicle

Field-oriented control (FOC) is the cutting-edge approach for optimizing the performance of the Permanent Magnet Synchronous Motor (PMSM) in Electric Vehicles (EVs). This technique excels by independently managing torque and magnetic field control. In this research, a PMSM is employed to propel a computer-simulated rear-wheel-drive vehicle. To guide the driver model, the Indian Drive Cycle (IDC) is utilized as a reference for vehicle speed. The control of current on the direct axis (id) and quadrature axis (is) is carried out with separate closed-loop systems to attain the desired speed and torque. This approach facilitates precise alignment of the magnetic fields of the stator and rotor, resulting in numerous benefits, including heightened efficiency, enhanced control over speed and torque, decreased energy consumption, and smoother overall operation. This research offers an extensive exploration of FOC for PMSMs in EVs, enclosing fundamental principles, merits, and practical considerations for implementation in the current trend. The FOC for PMSMs in electric vehicles is simulated using MATLAB/Simulink.
