Research on drive technology and control strategy of Electric Vehicle based on SVPWM-DTC

Drive technology and Control System of Electric Vehicle with TMS320LF2407A DSP as microcontroller are mentioned in this paper.The system takes permanent magnet syncronous generator as the driving motor, utilizing the direct torque control technology of SVPWM. Electric Vehicle are rearly driven by two wheels, which only needs to control one permanent magnet syncronous generator, and then it will be driven by mechanical differential and gearing. Direct torque control technology utilizes torque(current), control scheme of the double closed-loop of speed and Fuzzy Pi control algorithm, which shall have a better static and dynamic performance.
