【Abstract】 According to the technical requirement of 4 kW Permanent Magnet Synchronous Motor (PMSM), which is used for the pulse-on of the hybrid-electric vehicle, a vector control system is presented in the paper. The SVPWM arithmetic is adopted for the design of the system, which is based on DSP and includes the current detection, speed detection. Following the result of testing, the rise time of the speed is 0.1s and the overshoot of the speed is below 4%. The result proves that the control system can meet the requirements of the pulse-on of the electric vehicle.更多还原
