摘要
该文设计了一种以单片机为控制芯片,霍尔传感器为测速元件的直流电机闭环调速系统。系统采用一种PWM脉冲宽度调制技术和PID控制算法相结合的控制方法,可以实现直流电机的无极调速和稳速控制。系统具有结构简单,稳定性好,超调小,响应快,高精度等优点。
This paper designed a kind of with the single chip processor as the control chip,hall sensor as the velocity component of dcmotor closed-loop speed control system.System adopts a PWM pulse width modulation technology and PID control algorithm with the combination of control method,can realize the infinite dc motor speed control and the steady speed control.System has a simple structure,good stability,small overshoot,fast response,high precision,etc.
