The design method of single closed loop DC motor speed control system based on the algorithm of PID is intro-duced in this paper . In order to solve the problem of long adjustment time and the poor anti-interference in the DC speed control system , MCU STC89C52 was selected as the controller; the hardware of the system has been designed ultimately . In this paper , the pulse width modulation ( PWM ) technique is used to realize the DC motor speed control . The experimental results show that , the con-trol system has good dynamic and static performance , and has the strong robustness to load changes .
