This study is to propose a new control strategy to improve dynamic performance of the traction motor in the electric vehicle (EV) which is under command of considerable dynamic controls. Desired electromagnetic torque is derived from the torque feedforward loop. By introducing the indirect vector control, the q-axis current is acquired with the known motor torque and d-axis current. Voltage feedforward loop is to achieve d- and q-axis voltages for SVPWM generation. Considering control precision, PID adjustors in small ranges are also included for dynamic compensation of feedforward loops. With consideration of various EV operation conditions, the Matlab-based simulation and DSP-based experimental setup are deployed to verify the proposed strategy. Various curves illustrate the outstanding response ability of the proposed strategy, compared to the conventional three-loop method.
