In this paper, the basic principle of double closed P WMsystem of velocity modulation is analyzed. The main flow chart and interrupt service for the digital signal processor （DSP） programming are given. The experimental results of this device show that the motor operates stably and reliably, and the system noise is low. The system has excellent performance, such as slight overshoot, rapid respond and good anti-disturbance, while can achieve the demand of infinitely variable speed transmission of torpedo DC motor.
