Abstract

The technique of space-voltage vector pulse width modulation (SVPWM) can reduce the motor torque ripple effectively and increase the voltage utilization ratio obviously, so it has been used in the motor control widely. A pressure closed-loop control system based on the digital signal processor (DSP) TMS320LF2407 is introduced, and the variable frequency variable voltage control strategy has been implemented with SVPWM. The tests and the application results on the spot show that the pressure control system with SVPWM has many merits such as simple realization, good running performance and safety.
