| 摘 要： | 该设计方案以STC12C4052单片机和MOS管组成的H桥为硬件基础而设计的PID算法直流电动机调速系统.STC12C4052单片机能输出两路占空比可控的PWM(脉宽调制)信号,通过改变占空比从而达到直流电动机调速的目的.测速传感器采用霍尔传感器测速,通过单片机中断采集传感器产生的脉冲以实现闭环控制.

| Abstract: | H bridge composed of STC12C4052SCM and MOS tube is used as the hardware foundation to design a PID algorithm DC motor speed control system in this design scheme.STC12C4052 microcontroller can output two way dutyfactor controllable PWM signal to change dutyfactor to achieve the purpose of DC motor speed control.Speed sensor is hall-effect sensor,which is used to realize the closed loop control when the microcontroller interruptedly acquires speed sensor pulse. |
