基于单片机的直流电机速度合成器

Electronic Differential of DC Motor Based on SCM

基于PIC16F876单片机的速度合成器,用于履带式机器人或车辆的左、右直流有刷电机的驱动。合成器接收速度和方向2个PWM输入信号,使用单片机内16位的计数器测出其脉冲宽度值。软件采用分段的方法合成出2路直流电机的速度和方向的数字信号,然后将此信号转变为电机的PWM驱动信号。

The speed synthesizer based on SCM PIC16F876, which applied to the left and right drives of brush direct current motor for tracklayer robot and vehicle. The synthesizer receives 2 PWM input signal of speed and direction, and synthesized 2-way PWM output for DC motor using the 16-byte counter in the SCM PIC16F876. The software adopted the subsection method to synthesize 2-way speed and direction data signals; and then the signals were translated into the PWM accumulation of the DC Motor
