摘要
脉宽调制(PWM)在直流电机调速中应用十分广泛.为了实现基于51单片机定时器功能的高精度脉宽调制直流调速,设计了硬件电路原理和程序流程,分析了单片机中断系统参数对PWM周期精度的影响,确定了定时器参数,用汇编语言实现脉宽调制占空比的计算.在每个PWM周期内,定时器参数要使定时器中断按照正确顺序产生,就可使系统正常运行,运用仿真软件验证了此设计方法的有效性和可行性.
Abstract
Pulse width modulation(PWM)is widely used in DC motor speed regulation.In order to realize high precision pulse width modulation DC speed regulation based on 51 single chip microcomputer timer function,the study designs the hardware circuit principle and program flow,analyzes the influence of single chip microcomputer interrupt system parameters on PWM cycle accuracy,determines the timer parameters,and calculates the pulse width modulation duty cycle by assembly language.In each PWM period,the timer parameters can make the timer interrupt in the correct order,so that the system can run normally.Simulation software is used to verify the validity and feasibility of this design method.
