Abstract: Introduction was made to the working principle of direct current speed control based on microcontrollers. A direct current speed control system was designed based on AVR microcontroller. The AVR microcontroller has its own input capture and A/D conversion functions, which accurately and conveniently tested the motor speed and current, generating pulse width modulation waves to control the motor. The experimental results show that the adopted control plan combined software debugging with hardware debugging to make the system following and anti-disturbing better.
Key words: AVR microcontroller; direct current speed regulation; following performance; disturbance rejection
