    • Abstract
  • In view of problems of bad precision and anti-interference ability existed in PWM control system of DC motor based on single-chip microcomputer and being difficult to meet with requirement of real-time performance existed in PWM control system of DC motor based on DSP, the paper proposed a design scheme of PWM control system of DC motor based on FPGA. It detailedly introduced implementing principle of the system in four operation states of strong acceleration, weak acceleration, deceleration and constant speed of DC motor. The simulation result showed that the system has certain feasibility and can be applied in speed-regulation control system of DC electric locomotive of coal mine underground.
