摘要
本文设计了以单片机AT89S52为控制核心,以L298作为驱动的PWM直流调速系统。系统采用数字PID控制算法,实现了转速的闭环控制。系统可通过键盘设定电机的状态和期望转速,同时实时数码显示转速。
A signal closed loop speed regulation system of Pulse Width Modulation(PWM) for DC motor composed of microcontroller AT89C52 and L298 was designed.In this system,digital PID was used as the control algorithm,and status and expectation speed of the motor can be set through the keyboard,the motor speed can be shown on LEDS in real times.
