| Abstract: | A kind of speed regulation system for DC motor composed of PIC16F877 microcontroller and L298 was described. This system uses photoelectric coder as speed detecting sensor, uses digital PID control method, and uses PWM signal as control output to regulate DC motor speed. And the setting of relative registers of PWM regulating speed in PIC microcontroller was introduced. The hard circuit and software design were given. |
