Design of DC Motor PWM Speed Control System Based on STM32

In order to control PMDC(permanent magnet DC)motor’s speed accurately and rapidly and stab-ly,a control algorithm which integrating integral separation PID with variable parameter PID was proposed and a PWM speed control system for the DC motor was designed.The working principle of this DC motor speed control system was elaborated,including the newly-proposed control algorithm and the design of the system’s hardware and software.Establishing a STM32 chip-cored control platform to verify speed control system’s per-formance shows that as compared to the classical PID,this speed control system has faster response speed and better stability.
