【Abstract】 By analyzing the basic principle of voltage space-vector pulse width modulation (SVPWM), a sort of digital arithmetic is expatiated and the hardware and software of frequency regulating speed system for SVPWM are designed with DSP as its core in this paper. The results of experiment indicate that the system has a higher control precision and better dynamic capability, and the system can decrease obviously current harmonic component of inverter and harmonic wear of motor, and debase torque bouncing.\;更多还原
